摘要: Abstract The transmission and emission spectra of CaWO 4 /(1 × 10 -4 ) Pb crystals are measured. In Pb-doped an additional relatively sharp absorption broad band observed. is attributed to electronic transitions within the 2+ -ion, in WO 2- -complexes stabilized by neighbouring -ions. Quenching produces new bands which ascribed higher tungstate complexes. optical discussed a MO-diagram
