Получение наноструктурированных порошков иттрий-алюминиевого граната для светодиодов

Abstract

The variants of low temperature synthesis of nanostructure powder on basis of cerium contained YAG codoped by manganese and silicon ions are worked out. The powder compositions in system Y2О3-Al2О3 are defined with assistance of x-ray diffraction. The yellow light-emitting phosphor with composition Y3Al5О12: Ce, (Mn, Si) was produced as a result of precipitation method and a single-step auto-combustion process. The luminescence yield is almost analogous to the samples made from other conventional methods. Hence, it could be good candidate for generating white light when coupled to a blue light-emitting diodes.
