Cadmium tungstate (CWO) films on glass substrate have been first prepared by hydrothermal method at temperatures ranging from 120 to 180 degrees C from cadmium nitrite and tungstic acid in hydrogen peroxide solution. Crack free and dense CWO films with textured structure and thickness up to 8 micro m were formed at 150 and 180 degrees C as revealed by x-ray diffraction (XRD) and scanning electron microscoy (SEM) studied. Photoluminescence (PL) measurements revealed that highl textured CWO thick films possess better PL property. The growth mechanism and preferred orientation or textured structure as well as the relations between textured structure and PL property have been discussed.
