Highly thermostable white-emitting Ca₉ZnK(PO₄)₇:Ce³⁺,Dy³⁺ single-phase phosphor with tunable photoluminescence and energy transfer

Abstract

Recently, white light-emitting diodes (WLED) fabricated with single-phase white phosphor have become a popular strategy for lighting and display. Here, a single-component white-emitting micro-sized powder Ca9ZnK(PO4)7 (CZKP):Ce3+,Dy3+ with high thermal...

Anti-thermal quenching phosphors based on the new phosphate host Ca3.6In3.6(PO4)6

“…Phosphate is widely recognized as a critical matrix material for the production and enhancement of anti-thermal quenching phosphors due to its strong bonding networks, high structural rigidity, and extremely high acceptance for lattice defects and thermal disturbance. [6][7][8][9][10] Some anti-thermal quenching phosphate phosphors have been explored in recent years, such as Na 3−2x Sc 2 (PO 4 ) 3 :xEu 2+ , BaMgP 2 O 7 :Eu 2+ ,Mn 2+ , SrIn 2 (P 2 O 7 ): Dy 3+ , and Tm. 3,[11][12][13] Based on the previous reports, 8,[14][15][16] the processes for improving the thermal stability of phosphors by surface coating and phosphor-in-glass (PIG) techniques are cumbersome and not easy to perform.…”
