Photoluminescence, reddish orange long persistent luminescence and photostimulated luminescence properties of praseodymium doped CdGeO3 phosphor

Dual mode NIR long persistent phosphorescence and NIR-to-NIR Stokes luminescence in La3Ga5GeO14: Cr3+, Nd3+ phosphor

“…The samples La 3 X-ray diffraction (XRD) analysis was studied with a powder diffractometer (Bruker D8) using Cu Kα radiation (λ= 0.154 nm) at a scanning rate of 0.2 o /min. 6 Photoluminescence (PL), PL excitation (PLE) spectra, afterglow spectra and decay curves were measured by a high-resolution spectrofluorometer (Edinburgh Instruments FLS920) equipped with a 500 W xenon lamp and a 808 nm LD as excitation sources at room-temperature.…”

“…Optical imaging technique has become an essential tool for the cancer research, clinical translation, and medical practice over the last few decades, due to its distinct merits of high sensitivity, portability, non-invasiveness, and time effectiveness [1][2][3].…”

Luminescent properties of a green emitting persistent phosphor CdGeO3:Tb3+

“…Apparently, the photoluminescence properties of CdGeO 3 host are much similar to that of CdSiO 3 compound [27]. Thus, CdGeO 3 host can be proved to be a self-activated matrix [28].…”

Effects of boric acid on structural and luminescent properties of BaAl2O4:(Eu2+, Dy3+) phosphors

“…, Dy 3? ) with various amounts of H 3 BO 3 addition, as converted from diffuse reflectance spectra of BaAl 2 O 4 using the Kubelka-Munk function [16]. It is obvious that sharp absorption Fig.…”
