Photoluminescence enhancement of ZrO2/morin nanocomposites

For the first time, a novel fluorescent material, ZrO2/morin nanocomposites were synthesized by a simple heat refluxing method, using ZrO2 nanoparticles and morin as the starting materials. The properties of the samples were characterized by transmission electron microscope (TEM), Fourier transformation infrared spectroscopy (FTIR) and photoluminescence spectroscopy. The results showed that chemical bonds had formed between the surface atoms of ZrO2 nanoparticles and morin molecules. The PL intensity of ZrO2/morin nanocomposites was much higher than that of both morin particles and ZrO2 nanoparticles. In addition, the effect of the morin concentrations on the photoluminescence of the nanocomposites was also investigated.
