Photoluminescence properties of Y5Si3O12N:Ce3+ blue-emitting phosphors for white LED

Synthesis, crystal structure and luminescence properties of a Y4Si2O7N2:Ce3+ phosphor for near-UV white LEDs

“…Moreover, the structures of the Y-Si-O-N compounds have not been completely identi-ed and studied, and limited interest has been given to the photoluminescence (PL) properties. [20][21][22][23] Although Zhiguo Xia et al 24 reported the preparation and luminescent properties of Y 4 Si 2 O 7 N 2 , they did not obtain a pure phase of Y 4 Si 2 O 7 N 2 . Furthermore, they did not investigate the crystal structure of Y 4 Si 2 O 7 N 2 or the relationship between the crystal structure and the luminescence properties.…”

Luminescence and energy transfer of Eu3+ or/and Dy3+ co-doped in Sr3AlO4F phosphors with NUV excitation for WLEDs

“…In order to obtain a higher CRI with an appropriate color temperature, a new approach using near-ultraviolet (NUV) InGaN-based LED chip coated with red/green/blue (RGB) tricolor phosphors was introduced. Until now, many phosphors suitable for NUV excitation have been reported including aluminates, sulfides, silicates, molybdates, oxynitrides/nitrides, and so on [7][8][9]. However, the currently used sulfide-based phosphors have low chemical stabilities against humidity and poor resistance against irradiation from InGaN chip.…”

Efficiency Enhancement of Bredigite‐Structure Ca14Mg2[SiO4]8:Eu2+ Phosphor via Partial Nitridation for Solid‐State Lighting Applications

“…Nowadays, new light‐emitting diode (LED) phosphors, including oxide, oxyfluoride, nitride, and oxynitride host lattices were used in conjunction with near‐UV and blue light sources. These phosphors have attracted a lot of attention because the eventual performance of white‐LED‐based devices strongly depends on the luminescence properties of the phosphors used.…”
