Opis

This book will discuss how glass and glass ceramic interact with light, both transiently and permanently. Ways that light permanently alter the properties of glass and glass ceramic like the color, refractive index, and mechanical and chemical behaviors will be included. Each photochromatic phenomenon will be discussed in detail from the physical and chemical origin to the method fabrication and ultimately to their utilization.
