Abstract. We study the optical properties of zinc-chromium (ZnCrO), zinc-manganese (ZnMnO) and zinc-cobalt (ZnCoO) oxide layers grown on sapphire substrates, using a pulsed laser deposition technique. The influence of target composition and post-growth annealing on the optical transmission of the films and their bandgap energy are analyzed.

Keywords: zinc oxides, pulsed laser deposition, optical transmission spectra

Анотація.  Вивчено оптичні властивості шарів цинково-хромового (ZnCrO), цинково-марганцевого (ZnMnO) і цинково-кобальтового (ZnCoO) оксидів, вирощених на сапфірових підкладках, використовуючи техніку імпульсну лазерного висадження. Проаналізовано вплив вихідного складу та післяростового відпалу на оптичне пропускання плівок і їхню ширину забороненої зони.
