摘要

采用1-十八烯作为高温反应溶剂

利用氯化铕和磷酸三丁酯制备铕前驱体。分别采用正三辛基膦和碲粉制备的碲前驱体

以及油胺和二水乙酸镉制备的镉前驱体

在200 ℃合成Eu掺杂CdTe量子点。实验发现随着反应溶液中Eu的含量上升

CdTe量子点的荧光峰发生显著红移

但Eu的含量过高则会导致量子点的荧光强度下降。

Abstract

Using 1-octadecene as high-temperature reaction solvent

Eu-doped CdTe quantum dots were synthesized. The europium precursor was prepared by dissolving europium chloride into tributyl phosphate. Cadmium precursor solution was prepared by dissolving cadmium acetate into oleylamine

and Te precursor solution was prepared by dissolving tellurium powder into trioctylphosphine. CdTe and CdTe:Eu quantum dot were obtained at 200 ℃. The experiment results indicate that the fluorescence peaks of the quantum dots show obvious red shift with the increasing of europium content

but extra europium will lead to the decrease of fluorescence intensity.
