Template Synthesis and Photoluminescence of ZnTe Nanocrystals

Abstract

This work presents the synthesis of zinc telluride (ZnTe) nanostructures using a template-assisted chemical deposition method. The process is based on preliminary ion modification of the substrate, followed by chemical treatment, enabling nanocrystal formation at room temperature without thermal annealing. This approach is compatible with various substrates and suitable for the development of multilayer optoelectronic structures. The photoluminescence (PL) properties of ZnTe nanostructures were studied as a function of deposition time. PL spectra, recorded at room temperature, revealed broad visible-range emission with distinct peaks associated with excitonic recombination, localized states, and intrinsic defects. The variation in synthesis conditions influenced both the position and intensity of these emission bands, indicating the possibility of tuning optical behavior through controlled growth parameters. The results confirm the effectiveness of the proposed synthesis technique for producing ZnTe nanostructures with adjustable photonic properties. The material exhibits high sensitivity to structural modifications, making it a promising candidate for use in photonic devices, sensors, and hybrid nanoscale systems. The low-temperature and scalable nature of the method further supports its applicability in the development of functional nanomaterials for advanced optoelectronic applications
