The effect of material structure such as length of photochromic side chain, glass transition temperature and molecular structure of azo units on LIB and SRG are studied. The optical formation of self-induced SRG on films of these materials is also presented. LA eng UL http://ijop.ir/article-1-38-en.html M3 ER -
