Persistent luminescence of zinc gallogermanates

Autor: Ka-Leung Wong, Celina Matuszewska, Tomasz W. Pańczuk, Peter A. Tanner

Publikováno v: Journal of Materials Chemistry C. 9:7200-7213

Zinc gallogermanate samples have been optimized for maximum performance by zinc depletion and three overlapping photoluminescence and persistent luminescence bands at 3.0, 2.6 and 2.4 eV are assigned to emission from F+ (2T1 → 2A1) and F0 (3T1, 1T1

Mn4+ – activated elpasolite fluorides K2LiBF6 (B = Al, Ga and In) are well-known red-emitting phosphors for white light emitting diodes (WLEDs) application. Such fluorides exhibit narrow emissions at around 630 nm under near ultraviolet (NUV) or bl
