摘要

通过配体交换法，CdS/ZnS 核壳半导体量子点（QDs）与三重发射体 1-萘甲酸杂化。基于三重-三重湮灭上转换（TTA-UC）机制，将杂化的量子点与作为紫外发射体的 2,5-二苯基恶唑（PPO）混合，在正己烷溶液中以 405 纳米的可见连续波激发，可获得峰值为 340 纳米或更长的紫外发射。在 405 纳米的激发下，固体在近紫外光谱区（380-395 纳米）显示出上转换发射。

Near UV photon upconversion in cast solid with quantum dot

CdS/ZnS core-shell semiconductor quantum dots (QDs) were hybridized with1-naphthalenecarboxylic acid, a triplet transmitter, by a ligand exchange method. UV emission peaked at 340 nm or longer was obtained by visible continuous-wave excitation at 405 nm in n-hexane solution by mixing the hybridized QD with 2,5-diphenyloxazole (PPO) as UV emitter, based on triplet-triplet annihilation upconversion (TTA-UC) mechanism. The same mixture but in tetrahydrofuran gave solid film by solution casting, and the solid showed upconversion emission in near UV spectral region (380-395 nm) by 405-nm excitation.
