In this study, CdWO4 nanoparticles with acetate base synthesized by hydrothermal method and their photoluminescence emission spectra were investigated. The photoluminescence PL results show a peak at 460 nm which is in agreement with the results of cadmium tungstate synthesized by cadmium nitrate as the starting materials. The FTIR spectra confirm the Cd-O, W-O and O-W bands in the CdWO4 structure. The X-ray diffraction pattern confirms the formation of single phase of monoclinic wolframite structure. Image obtained by SEM shows that cadmium tungstate synthesized as nano particles and agglomeration of nanoparticles with particle sizes less than 100 nm. The results show that cadmium acetate as a precursor can be used as a cheaper material for synthesizing cadmium tungstate.
