Colloidal synthesis of ZnTe nanocrystals by laser ablation and fabrication of hybrid light emitting device
Zinc telluride (ZnTe) nanocrystals (NCs) have generated the interest of researchers as an electrode material in hybrid light emitting devices (HLEDs) due to its potentially high capacity. However, due to the restricted fundamental charging capacity of the electrode materials, the available energy of existing nanomaterial light emitting devices remains enough for a wide range of applications. In this research, ZnTe nanocrystals were synthesized using Nd: YAG laser at energy 600 mJ by 150 pulse number to form a battery device out of ITO/ZnTe/TPD/Ni. The spectra of the ZnTe NCs were assessed using ultraviolet-visible (UV-VIS) and photoluminescence (PL). The results proved that the synthesized NCs were nanocrystalline structures. The energy gap (Eg) within ZnTe NCs regarded as (PL) spectrum has been identified to be about 3.6 eV. ZnTe NCs produced via laser ablation enhance the functionality of the HLEDs by increasing the carrier's charge mobility and, as a further benefit, by facilitating recombination processes inside ZnTe NCs with TPD organic polymer. In addition to lighting at 3V, current-voltage (I-V) specifications establish suitable environment as well as formation.
