The thermoinduced coloration system of fluorane/iodonium salt has been investigated. The kinatic studies of thermoinduced color development reaction in polymer film was performed. It was found that two different phenomena appeared in the relationship between reaction rate constant and temperature. A very low value of k〓(0〓mol〓·l·s〓) and very high energy of activation E〓(149 KJ·mol〓) observed in the region of low temperature, whereas a larger value of k〓(1~10 mol〓·1·s〓) and smaller energy of activation (E〓33 KJ·mol〓) displayed in the region of high temperature of 150℃.

研究了荧烷/碘鎓盐热致显色反应体系，进行了分子膜中热生色反应动力学的研究，发现热生色速度常数k〓和温度关系呈现二种不同情况：在低温区，k〓值很小（＜10〓mol·1·s），活化能很大（E〓=149KJ·mol〓）；而在高温区，k〓值较大（1~10〓mol·1·s），活化能较低（E〓=33KJ·mol〓），它们的转折点位于温度（T〓=119℃），表明高于T〓是进行热致显色反应的重要条件；考虑到它们用作热记录介质的可能，研究了熔融状态中热生色反应。

From the results of XPS, ESR and coloration feature, it was inferred that N was embedded into TiO_2 powders to form interstitial and substitutional N doping,and N doped in the part of oxygen vacancy was crucial to emerge visible-light activity. Moreover, N doping played a significant role in restraining reoxidation of oxygen vacancy.

XPS、ESR测试结果和粉体的显色特性表明：N元素可以由沉淀剂直接引入到TiO_2粉体中，形成间隙型和置换型N掺杂；N占据氧空位的位置对粉体的可见光吸收特性是必要的，同时氮掺杂还可抑制氧空位的再氧化。
