摘要：

Composite phosphor ceramics were fabricated for white light-emitting diodes (LEDs) employing the tape-casting. Benefiting from the superposition of different emission spectrum, wider emission spectra of composite ceramics were reached, result in a higher color rendering index (CRI) of ceramic-based WLED. The composite structure and fluorescent property of composite ceramics were analyzed and the optical properties of ceramic-based WLED were tested. A ceramic-based WLED with a maximum CRI value of similar to 83 was reached when (Ce,Gd):YAG and(Ce,Pr):YAG were employed for the composite ceramics. (C) 2017 Elsevier B.V. All rights reserved.
