Fading Kinetics Model of Photochromic Glass Containing AgX
AgX光色玻璃退色动力学模型

A fading kinetics model, T = 1-B-kC0exp(-bt), was deduced on the basis of transition probability, b, of silver colloid forming silver ion, the solutions of the model were given by applying the measured fading kinetics parameters with a computer, and the measured fading kinetics curves and the calculated fading kinetics curves of F-series photochromic glass containing AgX were compared. The results indicate that the fading kinetics model preferably explains the fading process of the photochromic glass, and the transition probability, b, accurately expresses fading rate of fading kinetics. The calculated curves and measured curves of fading kinetics of F-series photochromic glasses containing AgX are almost similar. So these results further prove that the fading kinetics model is effective to explain the fading process, and the theory as the basis of the fading model is correct.
