Quantitative Determination of the Effective Mn4+ Concentration in a Li2TiO3:Mn4+ Phosphor and Its Effect on the Photoluminescence Efficiency of Deep Red Emission Moreover, the effect of the existence of Mn2+, Mn3+, and Mn4+ ions on the photoluminescence efficienc...
Minami, "High-luminance TFEL devices using Ga2O3:Mn phosphor thin films prepared by a spray coating method," in Extended abstracts of the 11th international workshop on inor- ganic and organic electroluminescence / 2002 international conference on the science and technology of emissive displays and...
X-Ray analysis of N,N'-dibenzyl-N-(5,5-dimethyl-2-oxo-1,3,2 -dioxaphosphoranyl)-thiourea (1) and its dicyclohexyl analog (2) revealed important structural differences in the solid state. The thiourea moiety in 1 formed by the atoms S, C(... Janina Karolak-wojciechowska,Micha W. ...
This paper reports a new phosphor Cs2Zn3(P2O7)2:Mn~(2+) with a broad emitting band from 490 to 700 nm for the three different luminescence centers of Mn~(2+). The emission band at 10 K can be splitted into three Gaussian peaks at 511, 582 and 662 nm, corresponding to the Mn~...
Luminescent properties of orange emissive Sm3+-activated thermally stable phosphate phosphor for optical devices Rare earth ion activated orthophosphates have a great deal of interest due to their thermal stability for white light emitting diodes. In this regard, ther... BV Ratnam,M Jayasimhadri,K...
Reflection electron energy-loss spectra of layered metal-phosphor-trisulfides have been measured in both the pulse counting mode and the voltage modulation mode. Metal d electrons of transition-metal phosphor trisulfides as well as post-transition-metal phosphor trisulfides make little contribution to ...
Controlled processing of (Gd,Ln)2O3:Eu (Ln = Y, Lu) red phosphor particles and compositional effects on photoluminescence Synthesis of (Gd0.95xLnxEu0.05)2O3 (Ln = Y and Lu, x = 0–0.95) powders via ammonium hydrogen carbonate (AHC) precipitation has been systematically studied... Bin ...
Interestingly, further rapidly adding K2MnF6 into the co-precipitation reaction system of K2GaF5(H2O) results in stable anhydrous cryolite phosphor K3GaF6:Mn4+. The investigation of a possible formation mechanism unravels that hydrous K2GaF5(H2O) can act as an intermediate to transform into ...
For this reason TbAG:Mn phosphor, in principle, can be applied for conversion of LED's radiation in the orange-red spectral range. This conclusion also can be extended to TbAG:Mn,Ce phosphor with higher efficiency of luminescence in the mentioned range with respect to YAG:Ce and TbAG:Ce...
