Abstract

The results of analysis of In₂O₃ film cathodoluminescence (CL) spectra are presented in this paper. In₂O₃ films, aimed for gas sensor application, were deposited by spray pyrolysis from 0.2 M InCl₃-water solutions. The influence of grain size (10-60 nm), film thickness (20-400 nm), pyrolysis temperature (T_pyr=400-520 °C), and annealing in the air or nitrogen atmospheres (T_an =600-1100 °C) on CL emission of In₂O₃ is discussed. CL spectra of as-deposited In₂O₃ films were characterized by a broad band centered at λ ∼ 570-600 nm. The annealing of studied films leads to a considerable increase of CL intensity. High annealing temperature of In₂O₃ films (T_an > 850 °C) is being accompanied by the appearance of additional bands centered at λ ∼ 400, 550, and 650 nm, which are peculiar to single-crystalline In₂O₃ nanobelts, or nanowires with perfect crystal structure. It was concluded that the improvement of crystal structure and the decrease of the concentration of oxygen vacancies are the main factors determining the change of CL spectra of In₂O₃ films and the appearance of edge luminescence.
