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

No data

Comments:

Specimen not analyzed. should be strictly speaking labeled burbankite group (in the sense of Horvath – Lapis, Rivista 2000). Other possibilities for not analysed specimens: remondite(Ce), petersenite-(Ce), khanneshite and calcioburbankite.

Activator(s): Fe3+, Ce3+,  Sm3+,  Eu3+,  Dy3+,  Mn2+ ,  O*,  Nd3+,  

Peaks in the spectrum (nm):

Ce3+ repl. Ca2+ : 390nm 

Mn2+ repl. Ca2+ : 560nm

Comments on spectrum and activators:

Laser-induced photoluminescence was studied for burbankite group minerals hexagonal burbankite, calcioburbankite, khanneshite and monoclinic remondite-(Ce), remondite-(La), petersenite-(Ce), as well as for orthorhombic carbocemaite and strontianite from carbonatites and hydrothennalites of alkaline complexes from various regions of the world.

 

Burbankite was studied by steady-state luminescence spectroscopy and luminescence of trivalent REE, such as Dy, Sm and Nd, was found (Gorobets and Rogojine 2001)

 

All REE-rich minerals of burbankite group (REЕ2Оз ~ 10.5 wt%) are characterized by violet luminescence and their photo- and X-ray luminescence spectra always contail1 four bands of Sm3+.

Low-REE hydrothermal burbankites (RЕЕ2Оз < 3 wt%) are distinguished bу different luminescence colors (from whitish to violet) and the low intensive spectra without Sm3+ bands.

The essential differences in luminescence properties of indicated burbankites are determined bу concentration ratio of the luminogene donor (Се3+) and the luminogene acceptor (Sm3+). (Gaft)
