本文研究了三氮吲哚嗪(TAI)对三种卤化银乳剂增感染料水溶液的吸收光谱和荧光光谱的影响。研究表明TAI能使这些染料的各吸收峰强度增强,对容易形成J聚集体的染料来说,更有利于其J态光谱吸收;当三氮吲哚嗪的浓度达到一定值后,它能使染料H聚集体分解成单分子,利于单分子光谱吸收;结果说明染料的荧光发射也随溶液中TAI浓度的增大而增强。本文还讨论了产生这种现象的原因。
In this paper, the effects of triazine indomethazine (TAI) on the absorption and fluorescence spectra of three silver halide emulsion sensitizing dye aqueous solutions were studied. The results show that TAI can increase the intensity of each absorption peak of these dyes and is more beneficial to the J-state spectral absorption of dyes that easily form J aggregates. After the concentration of triazine indomethazine reaches a certain value, So that the dye H aggregate decomposed into single molecules, which is conducive to single-molecule spectral absorption; results show that the fluorescence emission of the dye also increases with the concentration of TAI in solution. This article also discusses the reasons for this phenomenon.
