| 中文摘要 | compounds of sr3al2o6: eu, sr4al14o25: eu, and baznsio4: eu were synthesized by high-temperature solid state reactions. the doping eu3+ ions were partially reduced to eu2+ in sr4al14o25: eu and baznsio4: eu prepared in an oxidizing atmosphere, n-2 + o-2. however, such an abnormal reduction process could not be performed in sr3al2o6: eu, which was also prepared in an atmosphere of n-2 + o-2. moreover, even though sr3al2o6: eu was synthesized in a reducing condition co, only part of the eu3+ ions was reduced to eu2+. the existence of trivalent and divalent europium ions was confirmed by photoluminescent spectra. the different valence-change behaviors of europium ions in the hosts were attributed to the difference in host crystal structures. the higher the crystal structure stiffness, the easier the reduction process from eu3+ to eu2+. |
