Luminescence Alchemy: "Bluelite" - UVc

 

FOV: 2.5" wide.

 

Calcium sulfide made by heating calcium carbonate with hardware store sulfur in molten salt. Copper (~0.1% mol) and sodium (~1% mol) were added as activators. - "Bluelite"

 

Source:

Ca......CaCO3 (prepared from CaCl2 and Na2CO3)

S.......Sulfur fungicide (Hardware store)

Cu......CuSO4*5H2O (HST)

Na......NaHCO3 (A&H Baking Soda)

NaCl....Mixing salt (Hardware store)

 

Suspected phosphor:

CaS:Cu+,Na+ (FL Blue,pink >UVab,c)

 

Shown under UVc light.

 

Key:
