摘要：

The Ce-doped (Gd, Y)(3)Al5O12 transparent ceramics with Gd3+ content of 0 to 80 mol% were fabricated using a solid-state sintering method under vacuum. Their phase compositions and structure parameters were checked by X-ray diffraction (XRD). Optical and luminescence characteristics were investigated and thoroughly discussed by transmittance, absorption spectra and luminescence examination. The Gd3+ ions were found of great importance to the band structure of crystal and energy state of Ce3+ in the garnet ceramics. Balanced Gd3+ admixture into the YAG lattice provided excellent color coordinates and CRI for the phosphor for warm white light illumination. This study provides an efficient approach to tailor the luminescence of the garnet phosphors. (C)2015 Optical Society of America
