Abstract
CdWO4 particles were synthesized by a hydrothermal process with or without surfactant. The particles have a pure monoclinic phase with the wolframite structure. CdWO4 particles show different morphologies with the assistant of different surfactants. Nanoparticles were obtained when there is no the addition of surfactant. Cetyltrimethyl ammonium bromide and sodium dodecyl benzenesulfonate play the key roles in the formation of nanorods and microspheres, respectively. CdWO4 particles with different morphologies have an emission peak in the blue wavelength range. The emission intensity of microspheres is higher than that of nanoparticles and nanorods. The results show that cetyltrimethyl ammonium bromide and sodium dodecyl benzenesulfonate alter the shape and size of resulting CdWO4 crystals.
