Abstract
A method of forming a metal oxide crystal structure having a peroxide defect and doped with an alkali metal or alkaline earth metal. The method involves growing the doped metal oxide crystal by thermally decomposing in an oxidizing atmosphere a liquid mixture of an alkali metal salt or alkaline earth metal salt and the metal oxide or a compound that can decompose to form the metal oxide under the thermal decomposition conditions.
