| 9. | 2 . the optical transmission spectra of batio3 thin films annealed at different temperatures on fused quartz substrates are measured . the bandgap energies calculated from their optical transmission spectra are larger than that of single crystals reported in the literatures , whereas for poor - crystallized films with lower annealing temperature , their bandgap energy values are much larger than that of single crystals
发现batio3多晶薄膜的光学带隙大于文献报导的单晶薄膜的光学带隙,对于结晶性好的薄膜,其光学带隙接近于单晶值,退火温度越低,结晶性越差,与单晶的光学带隙相差越大。 |
| 10. | The photocatalytic activity of the samples was evaluated by the photocatalytic oxidation of nitrogen monoxide in the gaseous phase and the photocatalytic decolorization of methyl orange solution in the aqueous phase , respectively . the titania thin films on fused quartz were prepared by lpd method and then calcined at different temperatures
