This special volume consists of eight chapters consisting of seven review papers and one research paper. “luminescence phenomena: an introduction” is the first chapter contributed by kvr murthy and hs virk. it explains the basic phenomenon of luminescence: “luminescence is "cold light", light from other sources of energy which can take place at normal and lower temperatures. the word luminescence was first used by a german physicist, eilhardt wiedemann, in 1888. in latin ‘lumen’ means ‘light’. the materials exhibiting this phenomenon are known as ‘luminescent materials’ or ‘phosphors’ meaning ‘light bearer’ in greek. luminescence is basically a phenomenon of emission of light from an insulator followed by prior absorption of energy from ionizing radiations like, x-rays, alpha, beta and gamma radiations.
