Synthesis and photoluminescence properties of oxynitride phosphors M0.98Si2O2N2: Eu0.022+ (M=Ba, Sr, Ca) using the cellulose assisted liquid phase precursor proce

Enhancing thermal degradation stability of BaSi2O2N2:Eu2+ for white light-emitting diodes by ultra-thin Al2O3 layer via atomic layer deposition

“…1a. It shows that the BSON particles are irregular and have a particle size of [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] μm. The median diameter (D 50 ) of the BSON particles is determined to be 8.5 μm.…”

“…Eu 2+ -doped MSi 2 O 2 N 2 (M = Ca, Sr, Ba) phosphors show excellent photoluminescence properties and good chemical stabilities [12][13][14]. They emit visible light from cyan to yellow depending on the species of alkaline earth metals and dopants [15][16][17].…”

Cation vacancy-boosted BaZnB4O8:xEu3+ phosphors with high quantum yield and thermal stability for pc-WLEDs

“…19 Furthermore, compared to sulfide red phosphors, nitride and oxynitride red phosphors offer superior chemical and thermal stability, but their preparation requires complicated synthesis procedures, expensive raw materials and so on. 20–23 And the preparation process of a fluoride red phosphor produces toxic hydrofluoric acid, which also limits its application. 24 Therefore, the urgent need persists for discovering and developing new, efficient, and stable red-emitting phosphors for near-UV excitation.…”

Molten Salt Synthesis, Characterization and Luminescence Properties of BaAl1.4Si0.6O3.4N0.6:Eu2+Green Phosphors

“…For example, β-sialon:Eu 2+ and MSi 2 O 2 N 2 :Eu 2+ (M = Ca, Sr, Ba) emit strong green colors. [18][19][20] It was found that the inclusion of nitrogen into the host lattices being activated by Eu 2+ or Ce 3+ shows absorption and emission at relatively longer wavelengths when compared to their oxide hosts. 21 The effect of nitridation via (SiN) + substitution for (AlO) + in MAl 2 O 4 (M = Ca, Sr, Ba) has been studied by Li et al, 21 and BaAl 2 O 4 was found to be a better host lattice for (SiN) + incorporation due to the large ionic size of Ba 2+ .…”
