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 emission materials consist of components emitting three primary colors (red, green and blue) or two complementary colors (orange or green), which can cover the entire visible region (380~750 nm). White light emitting gel with the solution flow character and solid plasticity has the advantages of low cost, easy processing and flexible use. Gelation of components with different emission colors will help the donor and receptor molecule to get closer, contribute to the dipole direction and overlap the emission spectra of the donor and the absorption spectra of the receptor, which promotes molecular energy transfer to achieve better performance of white light emitting. Here we focus on the resonance energy transfer and introduce the white light emitting gel with the receptor chromophore of organic compounds, organic metal complexes and rare earth metal ions. In the end the future prospects of white light emitting gel are proposed.

Key words: white light emitting, gel, energy transfer
