Database of luminescent Minerals


Chemical Formula:See WILLEMITE

Familly: Silicates

Status: NON APPR

Mineral for Display: No


UV Type Main color Intensity Observation Frequency
Mid waves (320 nm):      Orange
Short Waves (254 nm):      Yellow Strong

Phosphorescence (in the common meaning of the term) seen by naked eye:

No Data


= yellow fluorescing willemite (golden-yellow to orange)

Beta-willemite does show anomalous yellow, rather than green fluorescence;
the change in the luminescence is related to subtle, but consistent, structural differences with normal willemite. (see mindat)

Main Activator(s) and spectrum:

Most Common Activator: Mn2+

No spectrum for the moment

Best Locality for luminescence(*):
