YAG:Ce nano-sized phosphor particles prepared by a solvothermal method

Red enhanced YAG:Ce, Pr nanophosphor for white LEDs

“…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.…”

Fine-sized Y3Al5O12:Ce phosphor powders prepared by spray pyrolysis from the spray solution with barium fluoride flux

“…Due to insufficient mixing and low reactivity of raw materials, high reaction temperature above 1500 • C was required to prepare the phase pure YAG:Ce phosphor powders. Therefore, YAG:Ce phosphor powders prepared through conventional solid-state reactions had large size in the order of 5-20 m. To overcome the drawbacks of the conventional solid-state reaction method, liquid solution and gas phase reaction methods such as co-precipitation, sol-gel, solvothermal, combustion, spray pyrolysis have been developed [3][4][5][6][7][8][9][10][11]. The flux addition has great influence on the ion diffusions, crystallization process as well as on the formation of YAG matrix with good crystallinity in the solid-state reaction method.…”

Synthesis and luminescent properties of Dy3+:GAG nanophosphors

“…Matyusheuko et al [17] indicated that it is impossible to prepare GAG powder by the solid-state reaction method. However, in recent years, several wet chemical techniques such as co-precipitation method, sol-gel, combustion, hydrothermal synthesis, solvothermal synthesis, glycothermal method, and spray-pyrolysis synthesis were used to prepare the phosphor precursor at lower temperatures [18][19][20][21][22][23][24]. Although, phosphor materials synthesized by chemical methods have many advantages, i.e.…”
