Growth and spectra properties of Nd3+-doped PbWO4 single crystal

Controlled synthesis of different morphologies of BaWO4 crystals via a surfactant-assisted method

“…Recently, tungstate materials have attracted much interest because of their luminescent behavior, structural properties and potential application [10][11][12]. Among the tungstate materials, BaWO 4 is a potential material to be a universal Raman-active crystal for its high gain in both the steady state and the transient state [13,14].…”

Lanthanide molecular-based hybrids covalently bonded with silica: Photoluminescence and control of micromorphology

“…The different spectra correspond to diverse peak wavelengths (A 241 nm; B 248 nm; C 255 nm) which exhibit the difference in the covalency of terbium ions sites. In terms of Judd-Ofelt theory [23,24] and much previous work [25][26][27] concerning relationship among hosts, bonding forms of RE ions and the transition properties of these metal ions, it has been reported that along with the increase of the peak wavelength, a corresponding degree of covalency between lanthanide ions and ligands will be increased. As for A, most non-covalent interactions existed within Tb 3+ ions and the surrounding environments.…”

Simulation study of the defect models of Cr-doped PbWO4 crystal and Cr, La-co-doped PbWO4 crystal

“…In the past 10 years, extensive researches on doping or codoping in PWO with the impurity ions for effectively improving the luminescence and scintillation characteristics have been performed [4][5][6]. Recently PWO doped with Cr has attracted special interests due to its remarkable scintillation properties and potential applications as medical imaging sensors and laser media [7,8].…”
