Characterisation of YAG:Ce powders thermal treated at different temperatures

Red enhanced YAG:Ce, Pr nanophosphor for white LEDs

“…This calculated average lattice parameter is consistent with the reported result. X-Ray diffraction shows that the synthesised YAG:Ce and YAG:Ce, Pr nanophosphors exhibit identical XRD patterns corresponding to Y 3 Al 5 O 12 matching perfectly with the JCPDS (card No.33-40) data [4,9,12]. The XRD peaks of doped and undoped materials are similar since the level of impurity doping in our case is as low as 1-7% in the Y 3 Al 5 O 12 host lattice.…”

“…Because of the large crystal field splitting of the 2-D level of Ce 3þ ion in the garnet structure, YAG:Ce has a very efficient broad-band emission in the yellow spectral region when excited by blue light [4][5][6]. This property makes YAG:Ce a suitable yellow-emitting phosphor for the application to white LEDs by combining it with blue LEDs [7][8][9].…”

“…This property makes YAG:Ce a suitable yellow-emitting phosphor for the application to white LEDs by combining it with blue LEDs [7][8][9]. Synthesis of YAG:Ce phosphor/nanophosphor have been reported by methods such as conventional solid state reaction [10], hot pressing [11], autocombustion [9,12], co precipitation [13], aerosol processing [4], gel [5] and solvothermal method [14]. Synthesis and properties of YAG:Ce codoped with other rare earth elements like Pr, Eu, Sm and Tb in both bulk and nanoform has been reported [12,[15][16][17] where different synthesis routes such as solid state reaction, combustion and modified polyol process was employed.…”

Variation of emission color of Y3Al5O12:Ce induced by thermal treatment at reducing atmosphere

“…Yttrium aluminum garnet (Y 3 Al 5 O 12 :Ce, YAG:Ce) is a known phosphor showing an efficient long-wavelength, broad luminescence located around 530 nm [1][2][3][4]. This emission was shown to shift to the red with increasing Ce content [5].…”

High luminance YAG:Ce nanoparticles fabricated from urea added aqueous precursor by flame process

“…Y 3 Al 5 O 12 :Ce 3+ (YAG:Ce) is a yellow phosphor that is widely applied for solid-state lighting, lasers and display devices [1][2][3][4][5][6][7][8]. YAG, as host material, has a relatively stable lattice and a high temperature mechanical strength [9].…”
