Název v původním jazyce
Effect of pulsed laser annealing on optical and structural properties of ZnO:Eu thin film
Popis výsledku v původním jazyce
ZnO:Eu thin film fabricated by pulsed laser deposition was treated by pulsed UV laser. The effect of laser fluence from 70 to 125 mJ cm-2 on film properties was investigated. The results showed that the surface morphology was clearly modified and the film treated at laser fluence of 70 mJ cm-2 was more densified compared to the other annealed films. Laser treatment led to a reduction of carbon content and to a stoichiometric ZnO:Eu composition on the surface. Refractive index significantly decreased and extinction coefficient was blue shifted for higher laser fluences. Strong characteristic Eu3? transitions were obtained using excitation at 266 nm. The highest photoluminescence intensity was observed for the annealed film at a laser fluence of 70 mJ cm-2. The influence of ambient composition (N2 and O2) and temperature (room temperature and 150 C) to photoluminescence response was examined for optical gas sensor application.
