摘　　要：三维立体显示技术图像逼真,因能够实现实时交互和全视景、多角度观察而备受关注。在各项三维立体显示技术中,基于透明上转换发光材料的静态体成像技术优势最为显著。鉴于此,本工作中,利用熔融–冷却–热处理制备方法,得到了一种Er^(3+)和Tm^(3+)共掺α–NaYF4纳米晶氟氧化物透明玻璃陶瓷;利用Er^(3+)与Tm^(3+)之间的能量传递过程,使得电子选择性布居,Er^(3+)红光发射增强,实现了980 nm近红外激光器激发下的纯红光发射。借助自主搭建的三维立体显示原型器件,可实现高色纯、高稳定纯红光三维静态/动态显示,体现了所研发材料在新一代三维立体显示技术中的应用潜力。Introduction With the development of society,two-dimensional displays can no longer meet people’s needs.Three-dimensional displays can completely reproduce the scene of world,showing the depth of the object,the sense of hierarchy,and reality because the real world is also three-dimensional.At present,there are a lot of techniques to realize three-dimensional displays,including two-dimensional analog three-dimensional displays,binocular parallax stereoscopic displays,and three-dimensional stereoscopic displays.Nevertheless,two-dimensional simulation three-dimensional display does not produce physical depth of field;Binocular parallax stereoscopic display is limited because of the disadvantages of small angle zoom,causing visual fatigue,and needing to assistant equipment.In contrast,three-dimensional stereoscopic display technology has attracted attention due to its realistic display effect,real-time interaction,and multi-angle observation.Among the related technologies,the static volume display technology based on transparent upconversion luminescent materials shows the most significant advantages.Methods Appropriate composition design is a necessary condition for the nucleation and growth of fluoride nanocrystals in glass.In this study,rare earth doped pure red upconversion luminescent oxyfluoride transparent glass ceramics were obtained via the conventional melt-quenching-thermal annealing method.The glass compositions(in mole)are 60SiO_(2)-6Al_(2)O_(3)-7Na_(2)CO_(3)-19NaFxErF_(3)-yTmF_(3)-(8–x–y)YF_(3)(x=0–1.6%,y=0–0.4%).The raw materials are SiO_(2),Al_(2)O_(3),Na_(2)CO_(3)(Sinopharm Chemical Reagents Co.,Ltd.),and high-purity NaF,ErF_(3),TmF_(3),YF_(3)(Shanghai Macklin Biochemical Technology Co.,Ltd),which were weighed,mixed and ground in an agate mortar.The obtained mixtures were then placed in a sealed alumina crucible and melted at 1550℃for 45 min under ambient atmosphere.Subsequently,the glass melt was poured into a 200℃preheated copper mould and annealed at 400℃ for 5 h to relinquish the
