Effects of various fluxes on the morphology and optical properties of Lu3−xAl5O12:xCe3+ green phosphors

YAGG:Ce transparent ceramics with high luminous efficiency for solid-state lighting application

“…Luminescent ceramics build much higher thermal conductivity compared to that of epoxy packaged phosphors (always < 1 W/(m•K)). Ce-doped garnet is a promising material for green-emitting luminescent matrix [25], such as Lu 3 Al 5 O 12 :Ce (LuAG:Ce). However, LuAG:Ce involves element Lu, which causes high cost of this material.…”

Enhanced photoluminescence and energy transfer performance of Y3Al4GaO12:Mn4+,Dy3+ phosphors for plant growth LED lights

“…As an alternative, Mn 4+doped oxides [14][15][16][17] catch the public's attention due to its attractive luminescence properties of high-efficacy, low cost, high stability and eco-friendliness. Many strategies have been tried out to enhance the photoluminescence emission of Mn 4+ -doped phosphors, such as matrix solid solution modication, [18][19][20] codoped charge compensator 21,22 or uxing agent, 23,24 and energy transfer from sensitizer to activator. [25][26][27] Solid solution treatment is a common method in phosphor modication with many advantages such as increase lattice distortion and lattice rigidity.…”

Synthesis and characterization of micro/nano-structured BaHPO4/Ba3(PO4)2/Ba5(PO4)3OH phases and their luminescence

“…And in the CSS process, H 3 BO 3 , a powdered solid at room temperature, will melt into liquid at about 169 C, thus a liquid surrounding is created, which can provide more contact room for the solid-state raw materials BaCO 3 and NH 4 H 2 PO 4 so that they are sufficiently mixed and react better. [18][19][20] And nally, in comparison to CSS with 0% H 3 BO 3 (CSS0), CSS5 could produce powders with better crystallization.…”

“…In the growth process, H 3 BO 3 melts into a liquid phase, promoting the mobility and homogeneity of solid reactants to gain products with fewer surface defects on the one hand, and to eliminate the aggregation of solid-solid contact for the formation of well dispersed particles on the other hand. 18,19,31 Comparing Fig. 4-1 with 4-2, it should be emphasized that the particle sizes of as-synthesized Ba 3 (PO 4 ) 2 samples using the different methods were on different scales.…”
