Near-Ultraviolet-Induced Narrow-Band Emission Phosphors: Eu3+-Activated YCa4O(BO3)3 for Backlight-Display and White Light-Emitting Diodes
Source abstract
Abstract
Developing red emission materials with high efficiency, good thermal stability, and high color purity remains a challenge for phosphor-converted light-emitting diodes (LEDs) and backlight displays. Herein, Eu 3+ -doped YCa 4 O(BO 3 ) 3 (YCOB) phosphors with narrow-band red light emission were designed to meet simultaneously the above targets. All samples have strong red emission with high color purity under near-ultraviolet (NUV) excitation. The temperature-related emission spectra showed that the synthesized phosphors presented great thermal-emission stability with an activated energy of 1.26 eV. Meanwhile, YCOB:15%Eu 3+ had a high internal quantum yield (about 69.2%). The electric dipole–quadrupole interaction results in concentration quenching. The fabricated phosphor-converted LED emits warm white light with a high color rendering index (92.17) and a low correlated color temperature (4834 K), suggesting that the Eu 3+ -doped YCOB phosphors are promising candidates for white LEDs. This study provides new ideas for researchers to identify undiscovered high-efficiency phosphors by expanding the application range of nonlinear laser materials.
