A two-dimensional TiO₂ photonic crystal layer is fabricated on Y3Al5O12:Ce3+ (YAG:Ce) yellow ceramic plate phosphor (CPP) to enhance its forward emission. A triangle lattice pattern is defined by molecular transfer lithography with polyvinyl alcohol nanostructured templates. A 4.5 improvement in yellow emission is achieved from photonic-crystal-structure (PhC) patterned YAG:Ce CPP compared to a nonpatterned one. The PhC-patterned YAG:Ce CPP shows a collimated far-field intensity emission pattern compared to the random-patterned and nonpatterned one.
在 Y3Al5O12:Ce3+（YAG:Ce）黄色陶瓷板荧光粉（CPP）上制备了二维 TiO₂光子晶体层，以增强其正向发射。使用带有聚醋酸乙烯酯纳米结构模板的分子转移光刻技术定义了三角形晶格图案。与非图案化的 YAG:Ce CPP 相比，具有光子晶体结构（PhC）的 CPP 的黄色发射提高了 4.5 倍。与随机图案化和非图案化的相比，PhC 图案化的 YAG:Ce CPP 显示出准直远场强度发射图案。
