（SS-RTP）已经从各种各样的共轭有机化合物中观察到（1，2）。当分子吸附在合适的固体基质上时，会表现出这种现象。纤维素滤纸和色谱纸被认为是迄今为止最适用的RTF支持物（2，3）。通过将几微升分析物溶液施加到支持物上来制备样品。在磷光计中分析之前，样品被广泛干燥。SS-RTP早在1896年就已存在（1）。Roth在1967年（4）和Schulman和Walling在1972年（5，6）的最新研究首次揭示了RTF是大量极性和离子化合物的一般性质。自从这些报告出现以来，发射现象受到了相当大的关注，导致了许多物理和分析研究（1，2）。然而，这些报告都没有令人信服地定义RTF诱导的机制，从吸附在固体基质，如纤维素的分子。过去，RTF支持物和样品制备方法都是在反复试验的基础上严格选择的。了解这一机制将为开发新的RTF方法提供逻辑基础。
(SS-RTP) has been observed from a wide varietyof conjugated organic compounds (1, 2). Molecules exhibit the phenomenon when adsorbed on a suitable solid substrate. Cellulose filter and chromatographic papers are credited as the most appli-cable RTF supports to date (2, 3). Samples are prepared by the application of a few microliters of analyte solution to the supports. The samples are extensively dried prior to analysis in a phosphorimeter.SS-RTP has been known to exist as early as 1896 (1). Recent studies by Roth in 1967 (4) and by Schulman and Walling in 1972 (5, 6) first revealed that RTF was a general property of a large number of polarand ionic compounds. Since the appearance of these reports, the emission phenom-enon has received considerable attention, resulting in a num-ber of physicaland analytical studies (1, 2). However, none of these reports has convincingly defined the mechanism of RTF induction from molecules adsorbed on solid substrates such as cellulose. In the past, RTF supports and sample preparation methodshave been selected strictly on a trial and error basis. Understanding the mechanism would provide a logical foundation for the development of new RTF metho-dology.
