Summary: This study investigates the influence of fine structures of conduction and intermediate bands on the photoelectronic properties of NaBiO3·2H(2)O/NaBiO3·xH(2)O heterostructures using SPV measurement. The results show that the SPV intensity differences increase with temperature and peak around 110 degrees C, while treatment with ethanol leads to a significant enhancement in SPV intensity at 470 nm. The findings highlight the importance of SPV measurement in studying the microstructures of conduction and intermediate bands in heterostructures for potential applications in photovoltaic and catalytic materials.
