Review of the synthesis,characterization, and properties of LaAlO3 phosphors

In this review different methods of preparing lanthanum aluminate (LaAlO₃) phosphors are discussed. The molten salt method, the combustion method, the sucrose method, and the coprecipitation technique are the best methods for preparing LaAlO₃ phosphors with small particle size and high surface area by low-temperature synthesis. LaAlO₃ usually has a rhombohedral structure. It has good dielectric properties and, hence, is regarded as an attractive alternative to SiO₂ in microelectronic devices. LaAlO₃ phosphors have excellent chemical and thermal stability, mechanical durability, and exploitable optical and electronic properties, leading to a wide range of potential applications. LaAlO₃ phosphors doped with rare-earth ions have luminescence properties and can, hence, be used in optical display systems.     

A review report on medical imaging phosphors

The present review deals with the synthesis and characterization of different phosphors used in medical imaging. A comparative study of different synthesis methods and characterization is presented. The best method for synthesized phosphor is the solid state method because the morphology of the sample is very good. The photostimulated luminescence of the prepared sample has been represented by different authors. The best phosphor used in medical imaging is BaBrCl:Eu²⁺.
