Synthetic Fluorescent Mineral Experiment: Jackolite2 Pb Concentration Test - PHOS

FOV: 6" wide.

 

Jackolite2 phosphor experiment with different concentrations of lead. Melted on aluminum trays on a steel plate.

 

Suspected Jackolite2 reaction:

S + Na2CO3 + CaCl2 -> CaS + 2NaCl + CO2 + 0.5O2

 

Both samples were doped with a 0.2% mol concentration of Mn2+ from MnSO4. The left sample also contained a 0.0015% mol concentration of Pb2+ from PbNO3.

 

Suspected phosphor: CaS:Mn,Pb in NaCl

 

Contains:

CaS:Mn,Pb (FL+PHOS! Pinkish Orange, Orange >UVa,bc)

 

Shown in phosphorescent state after exposure to UVabc light.

 

Key:

WL = White light (halogen + LED)

FL = Fluoresces

PHOS = Phosphorescent

BL = 450nm,

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

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