Phosphorescence (in the common sense of the term) observable with the naked eye:

No data

Comments:

Variety Tawmawite or chromepidote, {Ca₂}{(Al,Fe³⁺,Cr)₃}(Si₂O₇)(SiO₄)O(OH) containing chromium.

Activator(s) and spectrum:

Activator(s): Cr³⁺,

No spectrum yet

Comments on spectrum and activators:

Tawmawite, variety of epidote containing Cr found in Burma, fluorescence probably due to Cr³⁺ (to be verified).

Best localities for fluorescence (*):

Tawmaw, Hpakant-Tawmaw Jade Tract, Hpakant Township, Mohnyin District, Kachin State, Burma (Var. Tawmawite, epidote containing Cr originally reported from Tawmaw, Myitkyina-Mogaung District, Kachin State, Myanmar);

(*)The data are not exhaustive and are limited to a few remarkable localities for fluorescence
