摘要

采用水法制备和有机胶体法制备了黄橙色发光ZnSe:Mn量子点。此外，还获得了具有核壳结构的胶体纳米晶体。利用吸收光谱和光致发光光谱(PL)对纳米颗粒进行了表征。所获得的量子点具有以下特征参数:吸收边在350 ~ 410 nm范围内;与掺杂剂发射相对应的PL峰在约590nm处达到最大值;得到的纳米晶体在57 ~ 70 nm的PL峰半峰全宽(FWHM)。

Synthesis of colloidal ZnSe quantum dots doped with manganese

Yellow-orange luminescent ZnSe:Mn quantum dots were synthesized via aqueous and organic colloidal synthesis techniques. In addition, colloidal nanocrystals with core-shell structure were obtained. These nanoparticles were characterized by absorption and photoluminescence (PL) spectroscopies. The obtained quantum dots can be characterized by the following parameters: absorption edge is in the range of 350-410 nm; PL peaks corresponding to dopant emission have maxima at approximately 590 nm; obtained nanocrystals exhibit full width at half maximum (FWHM) of PL peak in the range of 57-70 nm.
