Abstract

Abstract:

Ce∶YAG single crystal for white light emitting diode(WLED) was grown by Czochralski method. The structure and optical properties of samples were characterized by X-ray diffraction(XRD) and photoluminescence spectra. Ce∶YAG single crystal shows a 500—650 nm broad emission band around 526 nm(5d^{1 2}E_gГ₈_g→4f^{1 2}F_7/2Г₈_u) under blue light of 455 nm. The excitation spectrum of Ce∶YAG single crystal is made up of 343 nm(4f^{1 2}F_5/2Г₇_u→5d^{1 2}E_gГ₇_g) and 466 nm(4f^{1 2}F_5/2Г₇_u→5d^{1 2}E_gГ₈_g) excitation peaks. The Stokes shift is 2448 cm^-1. The Huang-Rhys parameter is 6.12. The Ce concentration of Ce∶YAG single crystal is related with colour coordinate of WLEDs made by Ce∶YAG single crystal with the red phosphor(650 nm), a best concentration range of Ce in Ce∶YAG single crystal is 0.034—0.066.
