High uv selectivity
WebApr 27, 2024 · The sharp cut-off edge and high UV–visible rejection ratio (≈17 times higher) indicate a self-powered flexible UV photodetector. This work provides an effective and versatile route to modulate the photoelectric performance of flexible electronic devices. Conflict of Interest The authors declare no conflict of interest. Citing Literature WebThe ECD has high selectivity, because the necessary voltage to cause an oxidation-reduction reaction depends on the component. The ECD has also high sensitivity, and is often used for measurement of biogenic substances such as catecholamine. Evaporative light scattering detector (ELSD)
