Abstract
Flowers-like SnO2 grown on carbon cloth (SnO2/CC) was synthesized via simple hydrothermal process. The flowers-like structure includes needle-like and columnar-like forms. The optical analysis of the SnO2/CC show strong absorption in near ultraviolet region. SnO2/CC based rigid photodetector was designed on Indium Tin Oxide (ITO) substrate. By simply transferring the SnO2/CC to a transparent polyethylene terephthalate (PET) substrate, flexible photodetector was also successfully manufactured. Both the rigid and flexible devices exhibited excellent photoconductive characteristic to ultraviolet light at 254 nm and 365 nm. Especially, the flexible photodetector exhibits higher switch ratio of 26.14 to as weak ultraviolet light signal as 600 μW/cm2 at wavelength of 254 nm.
