Abstract EN
Erbium ion- (Er3+-) doped ZnWO4 crystals were synthesized via a hydrothermal method with different erbium concentrations.
The prepared materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and Raman, UV-Vis, and photoluminescence (PL) spectroscopy.
For ZnWO4:Er3+ crystals, a pure phase of ZnWO4 was obtained without any evidence of impurity present.
The SEM images show that the grain size and morphology of ZnWO4:Er3+ material depends on the Er3+-dopant concentration.
The UV-Vis spectra of ZnWO4:Er3+ compounds exhibited an absorption band at about 323 nm (3.83 eV) stemming from the [WO4]2−.
Other absorption bands centered at 367, 379, 408, 490, and 522 nm are related to Er3+-ion transitions.
Room temperature PL spectra of the ZnWO4:Er3+ compounds exhibited visible emission at 515–540 and 545–565 nm corresponding to the 2H11/2−4I15/2 and 4S3/2−4I15/2 transitions of Er3+ ions, respectively.
