Microwave induced solution combustion synthesis of nano-sized phosphors

Vanadate Phosphors for Energy Efficient Lighting

“…Recently, the development of new methods for the synthesis of micro or nano phosphors may increase the probability for high effective rare-earth phosphors [39][40][41][42][43][44][45][46][47][48]. Solution combustion synthesis (SCS) has emerged as an attractive technique for the synthesis of high purity homogeneous and crystalline oxide powders at signifi cantly lower temperatures than the conventional synthesis method, because the starting materials which are used are homogeneously mixed in liquid phase and the impurities with low boiling points can easily get evaporated at high temperature generated instantly during exothermic reaction [49][50][51][52]. The main attractive features of SCS are that it is very simple, safe, cost-effective, and has the ability to produce materials with high purity and better homogeneity; also, it is energy and time saving.…”

Microwave-Induced Combustion Synthesis of Luminescent Aluminate Powders

“…For example, microwave radiations are immediately absorbed by the entire sample and interact from bulk to the surface leading to volumetric heating in contrast with conventional sintering in which heating takes place by radiation or conduction of the heat energy from the surface to the core. This process has been recently used for the preparation of various oxides as well as luminescent aluminates such as YAG:Ce and BAM:Eu (Chen et al 2009;Fu 2006;Jung & Kang 2010).…”

Synthesis and Luminescent Properties of M2V2O7: Eu (M=Sr, Ba) Nanophosphors

“…Solution combustion synthesis (SCS) has emerged as an attractive technique for the synthesis of high purity homogeneous and crystalline oxide powders at significantly lower temperatures than the conventional synthesis method, because the starting raw materials are homogeneously mixed in liquid phase and the high temperature generated instantly by the exothermic radiation can volatilize low boiling point impurities [16][17][18][19]. The attractive features of SCS are its ability to synthesize materials with high purity, better homogeneity and high surface area in a single step.…”
