摘　　要：研究了13种吨染料在滤纸基质上的室温燐光（RTP）性质。发现具有重原子取代基的荧光素本身能有较强的RTP发射。若以Ph（AC）2为重原子微扰剂，则所有染料均能产生不同强度的RTP信号。探讨了取代基对RTP发射的影响，测定了它们的RTP寿命。The room temperature phosphorescence (RTP) properties of 13 xanthene dyes on filter paper have been studied. It is found that the fluorescein dyes substituted with heavy atom have intense RTP, while the other dyes can give RTP only when perturbed by the heavy-atom agent Pb (Ac)2. In addition, the substituents have manifest effects on the RTP properties of the dyes studied.
