Low temperature route for synthesis of cadmium selenide quantum dots and their application in fabricating a QD-LED Conference Paper uri icon

abstract

  • The present study describes the effect of ageing time during the synthesis of oleic acid capped cadmium selenide quantum dots synthesized by the hot injection route and their use in the fabrication of a hybrid quantum dot light emitting device (QD-LED). This hot injection process has been carried out at the lower synthesis temperature of 140°C compared to the conventional temperature of ∼300°C. Fluorescent monodisperse quantum dots of size 3-5 nm and 8-10 nm have been obtained at an ageing time of 2 and 3 hours respectively. An attempt to fabricate a QD-LED has been carried out. Current versus voltage studies show a turn on voltage at 3.06 V with a current of ∼ 87 nA. Copyright © Materials Research Society 2014.
