Study of luminescent properties of Y2O3:Eu3+ nano particles synthesized by precipitation method in the presence of various surfactants

The effect of surfactant on the luminescent intensity of Y2O3:Eu3+ nano particles is described. Three kinds of different surfactants were used to synthesis Y2O3:Eu3+ nano particles via a simple modified precipitation process. These surfactants are PEG-g- Acrylic comb which are different from each other by the number of repeated groups. The results demonstrated that the number of repeated groups had a significant influence on the morphology and particle size distribution and consequently, the photoluminescence intensity will be changed. The SEM and TEM results showed that morphology of particles is changing from irregular shape to semi sphere one by using these surfactants. The other results showed that the precipitation temperature had vital effect on morphology and particle size.
