Abstract

We have successfully grown pure and Pr3+-doped NaGd(WO 4)2 (NGW) single crystals using the Czochralski pulling method. By employing a suitable rotation and pulling rates, good quality crystals of pure and Pr3+-doped NGW have been grown from the solution melt. Structural analyses of the grown samples are studied by X-ray diffraction (XRD). The x-ray induced emission spectrum shows a broad emission band in the wavelength range from 400 nm to 650 nm for the pure NGW crystal, while that of Pr3+-doped NGW crystal excited by X-ray was composed of eight bands. Emission spectrum of pure NGW crystal excited by 266 nm UV solid state laser was obtained at room temperature. The emission band includes two spectral regions: one consists of a wavelength band spanning 360 nm to 450 nm wavelengths peaking at 410 nm, and the other consists of a wavelength band spanning at 450 nm to 700 nm peaking at 530 nm, respectively.
