Luminescence from crystals is often anisotropic and it leads to the polarization behavior of luminescence from single crystalline particles, as exemplified here with the upconversion luminescence from a single NaYF4 nanodisk. Nanodisk aggregates exhibit polarization dependent luminescence with different polarization degrees, which depends on the orientation and distribution of nanoparticles.
晶体的发光通常是各向异性的，这导致了单晶颗粒发光的偏振行为，此处以单个NaYF4纳米盘的上转换发光为例。纳米盘聚集体表现出具有不同偏振度的偏振相关发光，这取决于纳米颗粒的取向和分布。
