ABSTRACT = {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 (E<sub>g</sub>) 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. },
