Significant reduction of cathodoluminescent degradation in sulfide-based phosphors

Abstract

Interactions of excited activators in rare earth and transition metal doped phosphors and their role in low energy cathodoluminescence J. Appl. Phys. 91, 153 (2002);

Red photoluminescence properties and crystal structure of sodium rare earth oxyborate

“…0.8512 (6) 0.2594 (9) 0.2795 (7) 2.1(2) O7 0.3645 (6) 0.1561 (7) 0.3338 (6) 1.4 (2) hedra sheets. Na atoms separate them along the a-axis.…”

“…To meet the demands of plasma display panels (PDPs) and Hg-free fluorescent lamps, phosphors with a high quantum efficiency and high vacuum ultraviolet absorption (VUV) are required. Until recently, conventional phosphors Y 2 O 2 S:Eu, Y 2 O 3 :Eu and YBO 3 :Eu are still research objects of PDPs phosphor materials [1,2]. During operation, unfortunately, sulfide phosphors degrade and disperse into the vacuum, rare earth oxyborates have chromaticity and quantum efficiency problems, thus hindering their application to VUV luminescent materials.…”

Red photoluminescence and morphology of Eu3+ doped Ca3La3(BO3)5 phosphors

“…BaMgAl 10 O 17 :Eu has low brightness [7][8][9][10]. Therefore, in order to improve the performances of PDPs devices, it is necessary to explore novel phosphors with high luminescent efficiency and stability.…”

Red photoluminescence and crystal structure of Sr3Y2(BO3)4

“…(Y,Gd)BO 3 :Eu has poor color purity because it displays an orange-red emission instead of a red one. BaMgAl 10 O 17 :Eu has low brightness [7][8][9][10]. Therefore, in order to improve the performances of PDPs devices, it is necessary to explore novel phosphors with high luminescent efficiency and stability.…”
