The chemical transformations of three barium cuprates, BaCuO2, Ba2Cu3O5.9, and Ba2CuO3, which are the precursors and decomposition products of the Ba-based family of superconducting cuprates, were studied through their Raman bands under various laser irradiation conditions in air. BaCuO2 was stable up to 3 mW/μm2. Ba2Cu3O5.9 transformed into BaCuO2 under laser irradiation of 2 mW/μm2 or higher. Ba2CuO3 transformed to Ba2Cu3O5.9, first under laser irradiation of ∼1 mW/μm2, then to BaCuO2 when the irradiation was increased to above 2 mW/μm2. At elevated temperatures in air, BaCuO2 seems to be the most stable of these barium cuprates and Ba2CuO3 the least stable.
