摘要: The emission and excitation spectra of the SrS: Pb 2+ SrSe: phosphors were measured at low temperatures. 3 A 1u → 1 1g band 374 or 392 nm is observed 80 K in addition to T 368 383 for , respectively. On these bands, phonon structures appear 6 K. zero-phonon line on grows under external magnetic field. sharp 351 assigned isolated center. mechanism high energy region explained as transfer from host crystal an unexcited ion. It confirmed that rigid rotator model which explains admixture between states also available complex (S 2- ) (Se phosphors.
