The extinction behavior of various-shaped and core-shell-structured lanthanum hexaboride (LaB₆) nanoparticles was theoretically studied based on the discrete dipole approximation method. It was found that different nanoparticle shapes yielded a great influence on extinction efficiency. In comparison to spherical and cubic particles, the near-infrared (NIR) extinction peak of rod-like nanoparticles appeared at a longer wavelength. For core-shell-structured LaB₆ particles, all of LaB₆@TiO₂, LaB₆@ZnO, and LaB₆@SiO₂ exhibited low extinction in the visible region and high extinction in the NIR region, indicating that these three structures are potential transparent heat-shielding materials. Moreover, LaB₆@TiO₂ manifested better NIR extinction behavior than LaB₆@ZnO and LaB₆@SiO₂; however, its transmittance in the visible region was slightly reduced.

基于离散偶极子近似方法，从理论上研究了各种形状和核壳结构的六硼化镧（LaB ₆）纳米粒子的消光行为。发现不同的纳米颗粒形状对消光效率产生很大影响。与球形和立方体颗粒相比，棒状纳米颗粒的近红外 (NIR) 消光峰出现在更长的波长处。对于核壳结构的LaB ₆颗粒，所有的LaB ₆ @TiO ₂、LaB ₆ @ZnO 和LaB ₆ @SiO ₂在可见光区表现出低消光，在近红外区表现出高消光，表明这三种结构是潜在的透明隔热材料。此外，LaB ₆ @TiO ₂表现出比LaB ₆ @ZnO和LaB ₆ @SiO ₂更好的NIR消光行为；然而，它在可见光区的透射率略有降低。
