自由基照像光显影研究——能量转移机理及动力学
摘要:
研究了重原子化合物及各种气氛对四溴化碳-无色结晶紫自由基片光显影速度的影响。当片子中有重原子化合物碘仿,对碘苯胺或三苯基铋,或者片子置于氮气中光显影时,显影速度明显增加;在氧气中显影速度大大下降。氮气中的显影速度常数K0。与氯氧混合气体中显影度常数K满足如下关系: K0/K=1+a[O2]式中a为淬灭常数。因此,证明是三线态-三线态传能。实验证明,在光显影主期中,满足D=D0+Kt动力学关系。式中D为光密度,D0为光密度常数,K为光显影速度常数,t为显影时间。

STUDY ON THE OPTICAL DEVELOPMENT OF FREE RADICAL PHOTOGRAPHY——THE ENERGY TRANSFER MECHANISM AND KINETIC
Abstract:
The effects of heavy——atom compounds and atmospheres on the opticaldevel opment rate of CBr4-LCV (Leuco Crystal Violet) free radical film have been studied. It was found that the development rate is. increased in the presence of heavy-atom compounds:CHI3, p-iodoaniline and triphenyl-bismuth in the film or the optical development proceeds in nitrogen and is decreased when the film is developed in oxygen, indicating the possibi-lity of T-T energy transfer mechanism. The ratio of rate constant K0 innitrogen to K in the mixture of N2/O2 follows the equation K0/K=1+α[O2] where α is the quenching constant. In the main period of the optical development the following relation-ship between optical density(D) and time(t) is also found to be existed D=D0+Kt, where D0 is the experimental constant, K and t are the optical development rate constant and time, respectively.
