“…This means that the transition from CB for CdS to HOMO for poly-TPD does not happen because of the increase of the diffusion current for poly-TPD but the exciplex generation increases [24]. The peak 407nm of the poly-TPD/CdSNPs/Alq3 spectrum corresponds to TPD emission due to the fact that those peaks' energy equals TPD's band gap which is 3eV; this energy gap value was calculated using the EL wavelength peak (E = 1240/λ) [25]. The 407nm peak appears when using NPs where Auger-assisted energy that results from the nano-sized materials results in causing high Auger recombination cross section.…”

A hybrid cadmium sulfide nanoparticles (CdSNPs) electroluminescence (EL) device was fabricated by Phase – Segregated Method and characterized. It was fabricated as layers of (ITO/poly-TPD:CdS ) and (ITO/poly-TPD:CdS /Alq3). Poly-TPD is an excellent Hole Transport Layer (HTL), CdSNPs is an emitting layer and Alq3 as electron transport layer (ETL). The EL of Organic-Inorganic Light Emitting Diode (OILED) was studied at room temperature at 26V. This was achieved according to band-to-band transition in CdSNPs. From the I-V curve behavior, the addition of Alq3 layer decreased the transfer of electrons by about 250 times. The I-V behavior for (poly-TPD/CdS) is exponential with a maximum current of 4500 µA. While, the current is constant for (poly-TPD:CdS /Alq3) and the maximum current was 16.5 µA. Semiconductor nanoparticles like CdS are attractive for fabricating hybrid LEDs with spectrally pure color, low operating voltage values, and short-wavelength electro-luminescence, needed for the RGB devices. The correlated color temperature (CCT) was equal to (1700 oK) for the emitted blue light.

“…Among the II-VI semiconductor quantum dots (QDs), cadmium telluride (CdTe) is one of the most attractive candidates because of their size-dependent emission in a visible region and high photoluminescence (PL) quantum yield (QY) [7] The size-dependent properties make it especially suitable as building blocks for light-emitting diodes [8,9], photovoltaics [10,11], photonic crystals and bio-imaging [12,13], biological and chemical sensor applications [14,15], etc. Unlike other II-VI compound materials, CdTe can be prepared in both n-type and p-type conductivities [16,17], hence the facile route making of diode and field effect transistors possible. This permits the fabrication of solar cells in both homojunction and heterojunction configuration.…”
