Electroluminescent materialsElectroluminescence is the direct conversion of electrical energy into light energy of a solid luminescence phenomenon.In 1923, Loservi in the study of silicon carbide detector, found in the silicon carbide crystal applied a positive bias, will be accompanied by the pheno

Light-emitting materials, generally refers to materials that can emit visible light. It is said that during the period of Emperor Taizong of the Song Dynasty, the Japanese presented a painting, nothing could be seen during the day, but at night a lying cow could be seen. When we found out the reason

3 Combustion methodCombustion method is a method of synthesizing materials by combustion of precursors. When the reactants reach the ignition temperature of the exothermic reaction, ignition in some way, the subsequent reaction that is maintained by the heat released, the combustion products are the

1 high-temperature solid-phase methodThe use of high-temperature solid-phase reaction method for the preparation of long afterglow materials is a more traditional method, this method is more widely used. In general, the general operation of the solid-phase reaction is to solid powder as raw material
