The scattering effect plays an important role in improving the optical performance of the quantum dot (QD) white light-emitting diodes (LEDs). A majority of the previous studies incorporating nanoparticles have focused on the planar packaging (PP) structure and have not considered the semi-spherical lens packaging (SSLP) structure. Regarding the enhancement mechanism in the PP structure, nanoparticles significantly reduce the loss due to total internal reflection (TIR) by changing the direction of propagation of the TIR light. The SSLP structure has an advantage over PP structure due to higher light-extraction and negligible TIR loss; however, there is no literature referring to the incorporation of nanoparticles in SSLP structures. In this study, SiO2 nanoparticles are incorporated into QD-silicone encapsulation of LEDs with semi-spherical lens packaging (SSLP) to exploit their scattering effect.

散射对SiO钪纳米粒子量子点白光发光二极管光学性能的影响


散射效应对于提高量子点（QD）白光发光二极管（LED）的光学性能起着重要作用。之前大多数纳米粒子的研究都集中在平面封装（PP）结构上，而没有考虑半球形透镜封装（SSLP）结构。关于PP结构中的增强机制，纳米颗粒通过改变TIR光的传播方向，显着降低了全内反射(TIR)造成的损耗。 SSLP结构比PP结构具有更高的光提取和可忽略的TIR损失的优势；然而，没有文献提及在 SSLP 结构中掺入纳米颗粒。在这项研究中，SiO2 纳米颗粒被纳入采用半球形透镜封装 (SSLP) 的 LED 的 QD 硅胶封装中，以利用其散射效应。
