Studies on the sensitivity of dichromated gelatin ( DCG ) to blue and red light are reported. DCG sensitivity is improved when gelatin bias hardening is applied through the use of hardeners. Electron donors are found to increase the DCG light sensitivity. For hologram recording with a He -Ne laser, methylene green dye sensitizer is added and the role of dye concentration and pH of the solution is investigated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
