Considerable photoluminescence enhancement of LiEu(MoO4)2 red phosphors via Bi and/or Si doping for white LEDs

New Solid Electrolyte Na9Al(MoO4)6: Structure and Na+ Ion Conductivity

“…In addition to their use in Na ion batteries, double molybdates containing both alkali and trivalent cations are attractive for many industrial applications, including solid electrolytes, ferroelectrics, photocatalysts, and optical materials (white light-emitting diodes and solid state lasers). − The Na x R y (MoO 4 ) ( x +3 y )/2 ( R = trivalent cations) molybdates found in the Na 2 MoO 4 – R 2 (MoO 4 ) 3 systems are known to exist at a wide range of x : y ratios. The vast majority of the published Na x R y (MoO 4 ) ( x +3 y )/2 ( R = trivalent cations) molybdates exhibit 1:1 x : y Na: R ratios; nevertheless, there are also compounds with Na: R compositions of 5:1, 1:5, 3:1, and 9:1. , …”

Synthesis and photoluminescence of green-emitting Ce3+,Tb3+ co-doped Al6Si2O13 phosphors with high thermal stability for white LEDs

“…Besides, the shorter decay lifetimes of our products are bene-cial to avoid uorescence scintillating. 50 Additionally, we estimate the efficiency of energy transfer using the following formula:…”

Luminescent properties and energy transfer of Sm3+ doped Sr2CaMo1-xWxO6 as a potential phosphor for white LEDs

“…Compounds with tetrahedral MO 4 2-(M=Mo, W) groups have been studied and the broad CTB for O 2--M 6+ usually lies in 200 350 nm range [20,[22][23][24]. This limits excitation efficiency of the phosphors in near UV and blue region, where the most efficient LEDs are available today.…”
