Abstract:
In the present study, we report the preparation of CdTe quantum dots by chemical route followed by their characterisations with XRD, HRTEM, SEM and UV-Vis spectroscopy. Blue shifted sharp absorption edge is observed for the prepared sample and possess cubic crystallite with size ranging from 3 to 11 nm. It has been revealed that CdTe quantum dots are of emission (fluorescence) spectra occurring at a wavelength of 600 nm with narrow full width at half maxima. To test the function of CdTe quantum dot assembly as nano LED (nano light emitting device), the electroluminescence is studied and it shows the emission which is almost in the similar wavelength as that of fluorescence. This study infers the possible application of CdTe quantum dots as nano LED with an emission in at around 600 nm. Further, the emission intensity varies with the input bias voltage.
