Painterly fluorescence images
Greenland blue sodalite (collected by Mark Weller)
This image, taken with the rock under UVc (254nm Hg lamp) excitation, has a noticeably āpainterlyā appearance although it was taken in good focus and was not processes with any of the Photoshop āartisticā filters.
Looking at the fluorescing rock under a microscope shows why this happens. The UV photons enter the translucent crystals on the surface of the rock and excite fluorescence within their volume. As the fluorescent light emerges, it scatters and refracts in a way that largely obscures the surface topography, rather like looking at an object close behind a misted pane of glass.
This brilliantly coloured image shows this phenomenon particularly clearly.
FOV: 6" wide.

Porphyries are igneous rocks that display at least two distinct episodes of cooling. This is apparent by the very different sizes of the crystals that make up the igneous rock.
This video describes how porphyries form and 7 examples of porphyritic igneous rocks.
It ends with three UVC views of porphyries.

From the local rockshop (and antique store) comes this 4" tall antique medicine bottle. The bottle is an early 20th century bottle made by Grace & Rodinson between 1906 and 1932. (see: www.sha.org/bottle/medicinal.htm)
To enhance its transparency a bit of manganese dioxide (aka "glassmaker's soap") was added to the glass. The manganese oxidized the iron impurities and was itself, chemically reduced.
Under prolonged periods of UV radiation from the sun, the manganese was photo-oxidized which imparted a purple or pink hue to the glass. The purple of the bottle is very faint and was hard to photograph.
The oxidized manganese within the silica matrix of the glass fluoresces green under ultraviolet light much like willemite which contains Mn2+ impurities replacing zinc within the zinc silicate matrix. The tetrahedral cage of oxygen atoms in willemite results in an efficient absorption of UV light which allows the manganese ion to fluoresce in a very characteristic green color peaking at 525nm with no sensitizer required.
This is in contrast to minerals such as calcite and halite in which the Mn2+ ion is inside an octohedral cage of oxygen atoms (or chlorine atoms for halite) which makes UV absorption more difficult and so requires a sensitizer such as lead to make the manganese ion fluoresce in the characteristic red-orange color peaking around 620-630nm.
The fluorescence mechanism of the solarized glass appears to be similar to that of willemite. One major difference is that willemite is more active under UVc and less so under UVa which seems to be the opposite case for solarized glass. This may be explained by the fact that soda/lime glass is not very transparent to UVc and the amount of Mn ions in the glass is very small compared to the amount on the surface of willemite.
This experiment was inspired by the work of Bob Fosbury: see www.flickr.com/photos/bob_81667/6226788474/

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
Uranyl nitrate was combined with NaCl and recrystallized on a glass rod. (see previous expt.) This salt was recovered and dissolved in water. To this a solution of sodium carbonate was added. Water was added to increase the solution's volume to 60mL. This was used to rehydrate 45mL of DAP Plaster of Paris mix and the slurry was poured into a heart shaped mold.
The result displayed the blue-green fluorescent color common with uranyl minerals containing carbonate. Interestingly, the sample displayed much more phosphorescence than andersonite or "pseudo shrockingerite" both of which contain no sodium. Hydro-glauberite, on the other hand, is reported to phosphoresce green. The formula for hydro-glauberite is Na10Ca3(SO4)8*6H2O.
The result is shown next to some common opal containing the uranyl ion.

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
On the right ~15mL of calcined garden gypsum (rinsed) was combined with 7.5mL of a boiling solution containing sodium chloride, sodium carbonate and uranyl nitrate in an aluminum form. The mixture released much gas (CO2 ?).
On the left ~15mL of DAP Plaster of Paris (containing CaCO3) was combined with 7.5mL of the cooled previously mentioned solution after it had been treated with HCl to remove the carbonate ions. The still acidic solution reacted with the CaCO3 in the Plaster of Paris mix and was mostly neutralized by the CaCO3 becoming CaCl2 and CO2 gas (and H2O). The mixture was left to set in a plastic form.

From the basement lab comes this 2.5" wide specimen.
On an aluminum tray, salt {~15 mL}, washing soda and sulfur were heated until the salt had melted leaving a mustard yellow mass that smelled strongly of hydrogen sulfide.
On the sample was then placed a solution of calcium chloride containing a drop of MnCl2 sol and a drop of PbCl2 ssol. which was absorbed into the yellow mass turning it whitish. The sample was then reheated until the salt had melted.

T-type (Terlingua) calcite obtained from the Highland Rockshop (specimen presumably from N. Mexico) is shown here. This calcite is believed to contain organic activators which allows it to fluoresce pink under UVa, tan under UVb and blue under UVc with bright blue afterglow following exposure to UVa or UVb light.
This sequence shows the rhomb after it was heated on an electric coil of an electric stove set to HIGH for 30 minutes. The bottom shows the part of the rhomb that was not heated.

Uranyl nitrate and sodium chloride from a previous experiment was dissolved in water. Approx. 6mL of this solution was added to ~5mL of dry sodium metasilicate along with water in a small watch glass. This was rehydrated every few days for about two weeks as the sodium silicate would crystallize and then dissolve again. At the end of the two weeks it was dried under a small electric light bulb resulting in a clear glassy substance with a tinge of green color. On the surface formed large crystalline layer. Before the substance dried it was not very fluorescent. After drying and crystallizing, it became very fluorescent yellow-green under all UV wavelengths.
Because of the crystalline nature of the substance, I don't think I succeeded in creating hyalite opal which is amorphous and not crystalline.

This sample was doped with about 0.02ml of Cu2+ from malachite.
Suspected phosphor: CaS:Cu in NaCl
Contains:
CaS:Cu (FL+PHOS! Pink/Blue, Blue >UVa,bc)
Shown in phosphorescent state after exposure to UVabc light.
