Synthetic Fluorescent Mineral Experiment: Pseudo Schrockingerite rock - UVa

 

FOV: 3" wide.

 

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.

 

~15mL of DAP Plaster of Paris (containing CaCO3 and SiO2) was combined with 7.5mL of a NaUTC (sodium uranyl tri-carbonate) solution and allowed to set in a mold.

 

Contains:

"Pseudo Schrockingerite" (FL Blue-green >BL/UVabc)

 

Shown under UVa light.

 

Key:

WL = White light (halogen + LED)

FL = Fluoresces

PHOS = Phosphorescent

Blue = 450nm,

UVa = 368nm (LW), UVb = 311nm (MW), UVc = 254nm (SW)

'>' = "stimulated by:", '!' = "bright", '~' = "dim"

Much appreciation to Gordon Czop for the uranyl nitrate.
