白光发射材料由三种三原色(红、绿、蓝)发色体或一种三原色与一种补充色(橙色或者绿色)发色体组成,可以覆盖整个可见光区(380~750 nm).白光凝胶是一类具有液体流动性和固体可塑性的白色发光材料,合成成本低,易于加工,使用方式灵活.将不同发色团化合物凝胶化,有助于供受体分子的靠近、偶极方向的一致和供体发射光谱与受体吸收光谱的重叠,实现更好的分子间能量转移,获得可调控的白光.重点从能量转移的角度,介绍以纯有机化合物、有机金属配位化合物、稀土金属离子等作为受体发色团的白光凝胶的研究现状,并对其在白光显示、智能材料等领域的应用进行展望.
White light emitting material consists of three primary colors (red, green and blue) or a primary and secondary (orange or green) color body that covers the entire visible region (380-750 nm). White light condensing Gums are a class of white luminescent materials with liquid flow and solid plasticity, low cost of synthesis, ease of processing, and flexible use. Gelling different chromophore compounds helps to provide donor molecules with near-dipole directions And the overlap between the donor emission spectrum and the acceptor absorption spectrum to achieve better energy transfer between molecules and obtain tunable white light.From the perspective of energy transfer, this paper introduces the synthesis of pure organic compounds, organometallic coordination compounds, rare earth metals Ions as acceptor chromophore white gel research status, and its application in the field of white light display, smart materials and other prospects.
