| Description |
Light-emitting diodes (LEDs) with a broad spectral emission have been fabricated
using co-evaporated monolayers of cadmium sulfide (CdS) and cadmium telluride (CdTe)
nanocrystals in a hybrid organic-inorganic structure. The nanocrystals of CdS and CdTe were
grown by vacuum thermal evaporation technique. The incorporation of 50:50 ratio of CdS and
CdTe resulted in a broad emission spectrum with CIE coordinates (0.22, 0.33). The fine tuning
of the emission spectrum to achieve pure white light (CIE coordinates (0.30, 0.33)) was achieved
by incorporating a small quantity of 4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-
4H-pyan (DCM) dye in the device structure. The study indicates a promising route towards more
stable and efficient light-emitting devices for lighting applications.
