In this short topical review, a brief account of the evolution of defects due to controlled
changes in polycrystalline zinc oxide has been presented. X-ray diffraction, Positron …

ZnO films prepared at different temperatures and annealed at 900 C in oxygen are studied
by photoluminescence (PL) and x-ray photoelectron spectroscopy (XPS). It is observed that …

The correlation between the structural and optical properties of mechanically milled high
purity ZnO powder is reported in the present work. Reduction of average grain size and …

We investigated the effects of post-growth annealing in the temperature range of 873 to
1273 K on the spectral features of photoluminescence (PL) vis-à-vis the crystalline and …

Nanostructured ZnO thin films have been grown on quartz substrates by metal organic
chemical vapor deposition. Zn (tta) 2• tmeda (H-tta= 2-thenoyltrifluoroacetone, tmeda= N, N …

Porous nanocrystalline ZnO photocatalysts were successfully synthesized by microwave
irradiation and then thermally treated at different temperatures (150° C, 200° C, 250° C and …

The K doped and (K, Er) codoped ZnO thin films were prepared on glass substrate by sol–
gel method. The microstructures and optical properties of the doped and codoped films are …

Heterojunction diodes of n-type ZnO/p-type silicon (100) were fabricated by pulsed laser
deposition of ZnO films on p-Si substrates in oxygen ambient at different pressures. These …

Al-doped, zinc oxide (ZnO: Al) films with a 1.2 at.% Al concentration were deposited on p-
type silicon wafers using a sol–gel dip coating technique to produce a ZnO: Al/p-Si …

In this work, we report that (001) preferential orientation ZnO thin films with exposed holes
grown on Si (100), Si (111) and sapphire (001) substrates by magnetron sputtering are …
