Green remote phosphor films (RPFs) with different ZrO₂ microparticle concentrations for blue LEDs were prepared based on their strong scattering effect; the laminated white LED (WLED) with blue LED and red RPF was packaged further. XRD, SEM and double integrate sphere were used to test the RPFs. Results showed that ZrO₂ microparticles were evenly dispersed in the silicon resin, the scattering effect significantly improves the utilization rate of excitation light and the transmission intensity of emission light, and the phosphor conversion efficiency (PCE) had a maximum value of 79.35% when ZrO₂ concentration was 0.88 wt%. The laminated WLEDs test showed that the luminous efficiency (LE) reached a highest value of 150.38 lm/W at the same concentration, which has increased by 6.37%; ZrO₂ microparticles can adjust the color rendering index (CRI) changed from 86.5 to 89.1, the correlated color temperature (CCT) gradually decreased from 4613 to 4219 K, and the CCT uniformity increased by 5.59%. Research shows that ZrO₂ microparticles have potential application value in the preparation of high-quality WLEDs.

基于它们的强散射效应，制备了具有不同ZrO ₂微粒浓度的蓝色LED绿色远程荧光粉（RPF）。进一步封装了带有蓝色LED和红色RPF的层压白光LED（WLED）。XRD，SEM和双积分球用于测试RPF。结果表明，ZrO ₂微粒均匀地分散在硅树脂中，散射效应显着提高了激发光的利用率和发射光的透射强度，当ZrO时，荧光粉转换效率（PCE）的最大值为79.35％。₂浓度为0.88重量％。叠层WLEDs测试表明，在相同浓度下，发光效率（LE）达到最高值150.38 lm / W，提高了6.37％。ZrO ₂微粒可将显色指数（CRI）从86.5调整为89.1，相关色温（CCT）从4613 K逐渐降低至4219 K，CCT均匀度提高了5.59％。研究表明ZrO ₂微粒在制备高质量WLED中具有潜在的应用价值。
