UV–vis absorption spectra and Tauc analysis of (hνα)2 versus plots. (a) UV–vis absorption spectra of TiO2 nanorod arrays and TiO2/CdS core-shell structure with different cycles: (a) TiO2 nanorods and TiO2/CdS core-shell structure with (b) 10, (c) 30, (d) 70, and (e) 80 SILAR cycles. (b) Tauc analysis of (hνα)2 versus plots derived from the absorption spectra.
