Title: Luminescence properties of the Pb2MoO5 single crystals doped with Cu ions
Abstract: Photoluminescence (PL) emission and PL excitation spectra of the undoped and Cu- doped Pb2MoO5 grown by Czochralski technique are obtained and analyzed. The complex wide PL emission band in 450-750 nm spectral range was observed for both pure and Cu- containing crystals under photoexcitation with ultraviolet light. The short-wavelength component of the PL has been associated with luminescence centers related to MoO42− anionic groups. Long-wavelength the PL component with maxima near 600 nm was observed for both pure and Cu-doped crystals and it is described to manifestation of the crystal defects.
