Glycothermal synthesis and photoluminescence of Mg–Si modified Ce:YAG nanophosphors

The absorption spectrum of Ce in a YAG based host grown using the glycothermal method was modified using the addition of Mg-Si pairs. Photoluminescence intensity was dramatically improved by increasing the reaction temperature to 315 °C instead of the conventionally used 300 °C. It was found that Mg acetate and tetraethylorthosilicate (TEOS) are suitable as precursors for the glycothermal process, as EDS elemental mapping showed their …
