Abstract
Undoped beta -Ga2O3 single crystals were grown by the floating zone techniq ue under several mixtures of N-2 and O-2 gas at 2 atm pressure Cathodolumin escence spectra indicated the existence of five radiative transitions in th e wavelength region from ultraviolet to green. The emission efficiency was investigated as a function of the oxygen partial pressure during growth. Lu minescence increased with the; increase of the oxygen partial pressure, esp ecially for the green emission. (C) 2001 Elsevier Science Ltd. All rights r eserved.
