Summary: This study demonstrates the tuning of ZnO nanosheet-nanowire morphology by adjusting the NaOH concentration in a low-temperature chemical bath, resulting in a variety of nano/microstructures with different sizes and aspect ratios. Photoluminescence spectra were mainly influenced by violet emission from Zn interstitial related defects formed during growth. In dye-sensitized solar cells, ZnO nanosheets with a thickness of 30-40 nm exhibited superior performance in terms of J-V characteristics and transport dynamics.
