Electrical and optical properties of Al-doped ZnO and ZnAl2O4 films prepared by atomic layer deposition
ZnO/Al2O3 multilayers were prepared by alternating atomic layer deposition (ALD) at 150°C using diethylzinc, trimethylaluminum, and water. The growth process, crystallinity, and electrical and optical properties of the multilayers were studied with a variety of the cycle ratios of ZnO and Al2O3 sublayers. Transparent conductive Al-doped ZnO films were prepared with the minimum resistivity of 2....
متن کاملThe Effect of Annealing, Synthesis Temperature and Structure on Photoluminescence Properties of Eu-Doped ZnO Nanorods
In this study un-doped and Eu-doped ZnO nanorods and microrads were fabricated by Chemical Vapor Deposition (CVD) method. The effects of annealing, synthesis temperature and structure on structural and photoluminescence properties of Eu-doped ZnO samples were studied in detail. Prepared samples were characterized using X-Ray diffraction (XRD), scanning electron microscopy (SEM), particle size a...
متن کاملRoom-temperature violet luminescence and ultraviolet photodetection of Sb-doped ZnO/Al-doped ZnO homojunction array
A Sb-doped ZnO microrod array was fabricated on an Al-doped ZnO thin film by electrodeposition. Strong violet luminescence, originated from free electron-to-acceptor level transitions, was identified by temperature-dependent photoluminescence measurements. This acceptor-related transition was attributed to substitution of Sb dopants for Zn sites, instead of O sites, to form a complex with two Z...
متن کاملTemperature Dependent Excitonic Photoluminescence from Epitaxial ZnO Thin Films
We have studied the photoluminescence of highly transparent and c-axis oriented ZnO thin films grown on (0001) sapphire by Pulsed Laser Deposition at different temperatures ranging from 10K to 300K. We observed temperature dependent recombination from free excitons, bound excitons and LO phonon assisted free and bound excitonic transitions. The energies of free excitonic transitions are close t...
متن کاملOptical, Photoluminescence and Thermoluminescence Properties Investigation of ZnO and Mn Doped ZnO Nanocrystals
ZnO and ZnO: Mn nanocrystals synthesized via reverse micelle method. The structural properties nanocrystals were investigated by XRD and Transmission electron microscopy (TEM). The XRD results indicate that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. The various optical properties of these nanocrystals such as optical band gap energy, refractive index, dielectr...
