White-light-emitting-diodes (WLEDs) are all set for a bright future in the household and commercial lighting markets. Recently, white light emission from nanostructures has become the subject of research of general interest in order to replace the conventional phosphors of white light emission because of their size-tunable luminescence, high quantum yields and high photostability. Scientists now are working to enhance the efficiency of WLEDs and achieve cost effective synthesis of phosphors so that they can be used in everyday applications. My talk will focus mainly on the role of nanostructured materials in WLEDs.
