Abstract :
Bismuth oxide thin films are investigated. Two oxidation methods are compared: thermal oxidation in air and pulsed laser ablation (PLD) in oxygen atmosphere of bismuth targets, respectively. It is found that PLD-prepared films have simpler structure, more uniform morphology and slightly lower refractive index than those prepared by thermal oxidation.
