Commentaar over activators en spectra:

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 (REЕ₂О_з ~ 10.5 wt%) are characterized by violet luminescence and their photo- and X-ray luminescence spectra always contail1 four bands of Sm^3+.

Low-REE hydrothermal burbankites (RЕЕ₂О_з < 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)
