A novel approach to prepare zinc oxide films: excimer laser irradiation of sol–gel derived precursor films
TLDR
In this article, the structural characteristics, optical and electrical properties of the laser-irradiated films were investigated and compared with those of heat-treated films, and the differences in crystallinity and orientation were explained in terms of the thermal effect caused by laser irradiation.About:

Crystallization and Reduction of Sol-Gel-Derived Zinc Oxide Films by Irradiation with Ultraviolet Lamp
TL;DR: In this paper, structural changes in sol-gel films with photo-irradiation were investigated using zinc oxide (ZnO) derived from zinc acetate, and the exposure of the films to an ultraviolet lamp induced hexagonal ZnO crystals in a relatively dense amorphous structure.

Sol–gel-deposited ZnO thin films: A review
TL;DR: In this article, the main chemical routes used in the sol-gel synthesis of undoped ZnO thin films and highlights the chemical and physical parameters influencing their structural properties are summarized.

Metal oxides nanoparticles via sol–gel method: a review on synthesis, characterization and applications
TL;DR: In this article, the authors have explored a stable and efficient synthesis protocol of particularly four metal oxide nanoparticles: titanium dioxide (TiO2), tin oxide (SnO 2), tungsten oxide (WO3), and zinc oxide (ZnO) for getting desired chemical composition, nanostructure, and surface properties.

Polymorphic phase transition among the titania crystal structures using a solution-based approach: from precursor chemistry to nucleation process
TL;DR: This review sheds light on the stabilization/phase transformation pathways of titania polymorphs like anatase, rutile, brookite and TiO2(B) under a variety of reaction conditions.

Crystallization behavior and origin of c-axis orientation in sol-gel-derived ZnO:Li thin films on glass substrates
TL;DR: In this article, c-axis oriented lithium-doped zinc oxide (ZnO:Li) thin films were prepared on Pyrex borosilicate glass substrates by a sol-gel method starting from zinc acetate dihydrate, lithium chloride, 2-methoxyethanol and monoethanolamine.

Mechanisms behind green photoluminescence in ZnO phosphor powders
Karel Vanheusden,William L. Warren,Carleton H. Seager,David R. Tallant,J. A. Voigt,Bruce E. Gnade +5 more
TL;DR: In this article, the authors explore the interrelationships between the green 510 nm emission, the free-carrier concentration, and the paramagnetic oxygen vacancy density in commercial ZnO phosphors by combining photoluminescence, optical absorption, and electron paramagnetic resonance spectroscopies.
Journal ArticleDOI
Fabrication of green and orange photoluminescent, undoped ZnO films using spray pyrolysis
TL;DR: In this paper, photoluminescent, undoped ZnO films have been fabricated using spray pyrolysis of zinc nitrate solution using a polycrystalline hexagonal wurtzite type structure with no preferred orientation.
Journal ArticleDOI
Ultraviolet spontaneous and stimulated emissions from ZnO microcrystallite thin films at room temperature
TL;DR: In this paper, room temperature free excition absorption and luminescence were observed in ZnO thin films grown on sapphire substrates by the laser molecular beam epitaxy technique.

XPS and X-ray diffraction studies of aluminum-doped zinc oxide transparent conducting films
TL;DR: In this paper, an asymmetry in Zn 2 p 3 2 photoelectron peaks has been observed for aluminum-doped transparent conducting films, which has been attributed to the presence of excess zinc in the films.

Sol-gel-derived c-axis oriented ZnO thin films
TL;DR: In this paper, the structure, optical and electrical properties of ZnO films were investigated, and the c-axis lattice constants of the thin films and the band gap were shown to be a little larger than those of the crystal. But the differences between the thin film and crystal might be attributable to the grain boundaries and imperfections in thin films.
