Optical Properties of Co-BaTiO3/Mg(100) Nano-Composite Films Grown by Pulsed Laser Deposition Method

         

摘要

@@ Co nanoparticles embedded in a BaTiO3 matrix, namely Co-BaTiO3 nano-composite films are grown on Mg(100)single crystal substrates by the pulsed laser deposition (PLD) method at 650℃. Optical properties of the CoBaTiO3 nano-composite films are examined by absorption spectra (AS) and photoluminescence (PL) spectra.The results indicate that the concentration of Co nano-particles strongly influences the electron transition of the Co-BaTiO3 nano-composite films. The PL emission band ranging from 1.9 to 2.2eV is reported. The AS and PL spectra suggest that the band gap is in the range of 3.28-3. 7eV.
