Mineral for Display: No


UV Type Main color Intensity Observation Frequency
Short Waves (254 nm):      Green StrongVery rarely

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

UV Type Color Intensity Observation Frequency
Short Waves (254 nm): Green

Main Activator(s) and spectrum:

Most Common Activator: n[TiO6] cluster

Other activators:            (UO2)2+ (Uranyl ion) as impurities , Sm3+ , Dy3+ , TiO6 ,

Peaks in the spectrum (nm):

TiO : broad band peaking at 520 - 550nm 

Dy3+ : lines at 490nm 

Sm3+ : 549nm

No spectrum for the moment

Comments on activators and spectra:

Steady-state spectra of baddeleyite are characterized by bright green-blue luminescence which was ascribed to Ti impurity (Gaft et al. 1981a). Besides that, emission lines of trivalent Dy and Sm have been found (Eremenko and Khrenov 1982). (Gaft)

Activator: TiO6 (trace) with lines from Dy and Sm. Also possibly U.

Cathodoluminescence: greenish-blue (Khibiny);

Best Locality for luminescence(*):
