Hs. Gu et al., SYNTHESIS AND OPTICAL-PROPERTIES OF HIGHLY C-AXIS ORIENTED BI4TI3O12 THIN-FILMS BY SOL-GEL PROCESSING, Thin solid films, 283(1-2), 1996, pp. 81-83
Highly c-axis oriented Bi4Ti3O12 thin films have successfully been pre
pared on fused quartz substrates by sol-gel processing. The orientatio
n degree of the thin film was about 87%. The thin film exhibits good o
ptical transmission. The optical-absorption properties of the thin fil
ms have been measured. The variation of bandgap with annealing tempera
ture is studied.
