TLDR
In this article, the authors used laser ablation and magnetron sputtering to obtain high quality zinc oxide (ZnO) films by using special devised optical geometry, and proved that the traditional resonant cavity is not imperative to form the lasing and that in-plane closed loop paths via multiple scattering between crystalline grains seems more suitable to account for the LAS mechanism.About:

Green luminescent center in undoped zinc oxide films deposited on silicon substrates
Bixia Lin,Zhuxi Fu,Yunbo Jia +2 more
TL;DR: The photoluminescence (PL) spectra of undoped ZnO films deposited on Si substrates by dc reactive sputtering have been studied in this paper, where two emission peaks, centered at 3.18 eV and 2.38 eV, were found to correspond to oxide antisite defect OZn rather than oxygen vacancy VO, zinc vacancy VZn, interstitial zinc Zni, and interstitial oxygen Oi.

Localization of light in a disordered medium
TL;DR: In this paper, the authors proposed a disorder-induced phase transition in the electron-transport behavior from the classical diffusion regime, in which the well-known Ohm’s law holds, to a localized state where the material behaves as an insulator.

Photoluminescence and ultraviolet lasing of polycrystalline ZnO thin films prepared by the oxidation of the metallic Zn
TL;DR: In this paper, a simple method for preparing polycrystalline ZnO thin films with good luminescent properties was reported: the oxidization of metallic Zn films. But this method is not suitable for the case of light-sensitive materials.
