| 中文摘要 | lialo2 single crystals doped with ti at concentration 0.2 at.% are grown by the czochralskl technique with dimensions phi 42 x 55 mm. ti ions in the crystal are quadrivalence proven by comparing the absorption and fluorescence spectra of pure lialo2 and ti: lialo2. after air and li-rich atmosphere annealing, the absorption peaks in the range of 600-800nm disappear. we conclude that 682 and 756nm absorption peaks are attributed to the v-li and v-o absorptions, respectively. the peaks at 716nm and 798nm may stem from the v-li(+) and f+ absorptions. the colour-centre model can be applied to explain the experimental phenomena. ti4+-doping produces more lithium vacancies in the lialo2 crystal. the intensities of [lio4] and the associated bonds remain unchanged, which improves the anti-hydrolyzation and thermal stability of lialo2 crystals. |
