Abstract
SnO2 quantum dots are synthesized via chemical method and exposed to 100 MeV high energy Nickel ion beam (swift
heavy ion). The prepared quantum dot samples have been examined in a fabricated ZnO/QD based nano light emitting
device by studying the variation of electroluminescence with variation of supply voltage at room temperature. Higher value
of light emission and almost linear variation of EL intensity with voltage is obtained for irradiated quantum dots compared to
that of pristine ones. Thus swift heavy ion irradiated SnO2 quantum dots are better suited as high intensity light emitting
device at room temperature..
