ZrMOF@CdTe nanoparticles (NPs) with high fluorescence were synthesized by hydrothermal method. The morphology, particle size distribution, compositions, fluorescence properties and stability of the synthesized ZrMOF@CdTe were analyzed via the characterization by TEM, ICP-AES and fluorescence spectrophotometry, and the effects of the reaction time and pH value on the fluorescent property of ZrMOF@CdTe NPs were discussed. The results show that ZrMOFs could maintain its morphology and structure well during the process of loading CdTe quantum dots. With the increase of the loading reaction time, the red-shifted emission peaks of ZrMOF@CdTe NPs appear, and their fluorescence gradually changes from green to red color. With the increase of the pH value and temperature of the hydrothermal reaction, the fluorescence of ZrMOF@CdTe NPs was also consistent with the red-shifted change. The fluorescent property of ZrMOF@CdTe NPs could be remained for more than 3 months. Therefore, ZrMOF@CdTe NPs synthesized by the hydrothermal method have the characteristics of simple operation, adjustable fluorescent color and high stability, and the potential application in the fields of biological detection and sensing is expected.
