首次观察到下列LiYF4:Nd3+的光谱:用波长λ为4880?的Ar+激光激发的4I11/2能级所属斯塔克子能级Y1—Y6的电子和电-声子喇曼散射谱;用波长λ为6943?的红宝石激光激发的双光子荧光和电-声子荧光谱。The following spectra of LiYF4:Nd have been observed for the first time: (i) the electronic and electron-phonor Raman spectra of the stark sub-levels Y1-Y6 of energy levels 4I11/2 excited by 4880? Ar+ laser beam; (ii) two-photon fluorescence and electron-phonor spectra excited by 6943? ruby laser beam.
