Synthesis of Phosphorus-Based Phosphors

Abstract

AbstractThe present chapter describes phosphorus-based phosphor compounds focused especially, on their synthesis, properties and applications. One of the main properties of phosphor materials is the photoluminescence. The phosphorus-based phosphors have already many applications in medicine (imaging techniques) and also in high power light-emitting diodes (LEDs) as light source for illumination or plant growth, field emission displays (FEDs), cathode ray tubes (CRT), X-ray detectors, projection televisions (PTV), fluorescent lamps, laser technologies, plasma display panels (PDP), ultraviolet-visible photocatalysts or temperature sensing, and so on. The LEDs technology significantly reduced the energy consumption for electric lighting. By using novel phosphor compounds, high emission-efficient fields in displays and UV devices are already produced. On the last two decades the importance and therefore the interest for those compounds increased significantly. While most of them are synthesized via the classic solid-state method, in the last years other synthesis routes developed also, as for instance the combustion method, the sol–gel method, the precipitation method, the hydrothermal method, ultrasonic spray pyrolysis, extraction pyrolytic technique, hydrolysis, and decomposition.
