%X 采用水热法制备了NaYF4:Er3+/Yb3+纳米颗粒，利用FDTD对单个Au纳米棒的场强进行模拟，通过晶种子生长法制备了不同长径比的Au纳米棒，并将Au纳米棒复合到NaYF4:Er3+/Yb3+纳米颗粒中形成复合材料，利用局域表面等离子体共振增强效应实现NaYF4:Er3+/Yb3+上转换发光的发射和激发增强。当长径比为3:1的金纳米棒掺入量为3.2%时，上转换发光材料的发射增强强度整体增强了2.5倍，当长径比为5:1的金纳米棒掺入量为3.2%时，上转换发光材料的发射增强强度整体增强了5倍。
NaYF4:Er3+/Yb3+ nanoparticles were prepared using a hydrothermal method. The field strength of a single gold nanorod was simulated using the FDTD method. Gold nanorods with different aspect ratios were synthesized via the seed growth method and were incorporated into NaYF4:Er3+/Yb3+ nanoparticles to form a composite material. The localized surface plasmon resonance (LSPR) effect was utilized to enhance both the emission and excitation of the NaYF4:Er3+/Yb3+ upconversion luminescence. When gold nanorods with an aspect ratio of 3:1 were added at a concentration of 3.2%, the overall emission intensity of the upconversion luminescent material increased by 2.5 times. When gold nanorods with an aspect ratio of 5:1 were added at a concentration of 3.2%, the overall emission intensity of the upconversion luminescent material increased by 5 times.
