摘要
长余辉陶瓷具有物理化学性能稳定、余辉亮度高等优势,在应急指示、生物成像、光学存储等领域受到了广泛关注,其中长余辉透明陶瓷凭借其“体积效应”,有利于获得发光均匀性好、亮度高、余辉时间长的长余辉发光,具有较好的发展前景。本文回顾了各类长余辉陶瓷特别是长余辉透明陶瓷的国内外研究进展,阐述了长余辉陶瓷的制备工艺及其陷阱深度和余辉性能的调控方式,总结了长余辉陶瓷面临的主要问题并展望了其发展趋势。
Long afterglow luminescent materials have an intrinsic characteristic of emitting light continuously after being irradiated by excitation sources,which are widely used in the fields of emergency indicator,optical information storage,information encryption and bio-imaging,etc..Although long afterglow phosphor powders are extensively investigated,their unstable physical and chemical properties and self–absorption induced low afterglow brightness strictly limit their long-term developments.These bottlenecks can be overcome via applying long afterglow glasses,but the limited ion doping concentration in glass matrix could not conducive to the improvement of their afterglow brightness and afterglow duration.Contrarily,long afterglow ceramics of dense structure integrate the merits of both phosphor powders and glasses,and develop rapidly in recent years.Among them,long afterglow transparent ceramics are easy to achieve a desired luminescence uniformity,a high luminescence brightness and a long afterglow duration since their afterglow brightness and afterglow duration can increase with increasing the ceramic thickness(i.e.,volume effect),providing a considerable application prospect in the future.Therefore,it is of great significance to conduct systematic investigations towards the optimization of the optical and afterglow properties of long afterglow ceramics and long afterglow transparent ceramics as well as the development of their novel processing techniques.Long afterglow ceramics mainly include aluminate,garnet,sesquioxide and zinc gallate ceramics.Long afterglow aluminate ceramics are easy to achieve a long afterglow duration and a high afterglow brightness,and solid phase reaction method is a mainstream preparation technique of aluminate long afterglow ceramics.The impact of ion doping on the optical and afterglow properties is investigated.With the development of technology,new preparation techniques such as laser sintering and melt-quenching methods are also used to prepare aluminate long afterglow ceramics.L
