英文摘要	Herein, we demonstrate for the first time the synthesis of copper tungstate (CuWO4) crystal by a facile polyacrylamide gel route. X-ray diffraction patterns reveal that the pure phase CuWO4 obtained by calcining xerogel at 900 degrees C has the triclinic crystal structure. The component of prepared CuWO4 are further confirmed by the X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. Transmission electron microscope results demonstrate that the CuWO4 has high crystallinity. Ultraviolet-visible absorption spectra indicate that the samples have remarkable photoabsorption in the near-infrared region. Photoluminescence spectra show that the CuWO4 has an emission peak at 583 nm with excitation wavelength of 430 nm. The synthesized CuWO4 phosphors with attractive optical and photoluminescence properties have potential applications in photoelectric devices and lasers.
