Red Fluorescence Activators: Iron and Chromium - UVc

 

FOV: 6" wide.

 

The majority of the red fluorescing minerals seen on this photostream is calcite which is activated by impurities of manganese and lead (acting as a sensitizer). However manganese's neighbors on the periodic table, iron and chromium also can cause some minerals to fluoresce red.

 

Seen here is a collection of red fluorescing minerals, (from left to right): microcline (var. Amazonite), ruby and eucryptite. The microcline and eucryptite are activated by Fe3+ and the ruby is activated by Cr3+.

 

Contains:

Microcline (FL Red >UVc)

Ruby (FL Red >UVa)

Eucryptite (FL Red >UVc)

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"

 

The microcline and eucryptite were obtained from Polman Minerals

The ruby was obtained from obtained from UC Minerals
