氧氟微晶玻璃中稀土离子分布对红外发光性能的影响研究
Distribution of rare-earth ions in oxyfluoride glass-ceramics and influence on its infrared optical properties
摘要
Abstract
To realize the efficient infrared emission from rare-earth ions, it is essential to explore the distribution of rare-earth ions inside the fluoride nanocrystals. In this work, oxyfluoride glass-ceramics containing PbF2: Er3+ nanocrystals were prepared to investigate the distribution of rare-earth ions inside the fluoride nanocrystals.Structure and composition of these fluoride nanocrystals were examined by X-ray diffraction, high-resolution transmission electron microscopy and electron energy loss spectroscopy. Preferential incorporation of Er3+ions into the fluoride nanocrystals was evidenced by the electron energy loss spectroscopy analysis, and the enrichment of of Er3+was also observed.Y3+ions were introduced to reduce the enriched clusters of optical active ions inside the nanocrystals. Emission spectra showed that 2.73, 1.47 and 1.2 μm emission by Er3+, Tm3+ and Ho3+ ions were enhanced significantly.关键词
