Welcome to the nano group at the Department of Chemistry, Indian Institute of Technology, Delhi. The group was established in July 2008. We finally moved to our renovated lab in January 2010. Since then our group has been involved in the synthesis and applications of nanomaterials with an aim towards optical applications. The group is interested in studying the changes that can be brought about in nanomaterials as a function of various synthesis parameters. We develop a number of new nano-heterostructures and study the basic principles governing their charge dynamics. Through the links on this webpage, you will also find a number of bio-applications being developed based on these materials. We are also interested in developing materials for photovoltaics and photocatalysis. Please check here for updates on the activities of the group.
