Abstract :
Performed is a comparative study of the characteristics of YAG:Ce luminescent converters with single-crystalline, cellular and polycrystalline structure obtained by the method of directed crystallization of the melt. Peculiarities of the structure and surface morphology of the converters are found to essentially influence their spectral characteristics and luminescence efficiency. It is shown that polycrystalline converters based on YAG:Ce are promising for application in white light emitting diodes.
