Abstract
Barium oxide nanosizeparticles were prepared using the wet chemical route. Various capping agents were used to arrest the growth. X-ray diffraction studies reveal particle size as low as 9 Å in diameter, which is close to the Bohr exciton radius of BaO. However, changes in the optical absorption features arising from the confinement effect in the nanosizeregime were not observed. These results were confirmed by fluorescence measurements. The calculations based on effective mass approximations indicate that the quantum confinement effects are not significant for particle sizes as small as 15 Å.
