Abstract
- Photodetectors play a key role in the military, aerospace, communications, bio-imaging, etc. In this study, we fabricate photodetector devices based on (CH<subscript>3</subscript>NH<subscript>3</subscript>)<subscript>2</subscript>FeCuI<subscript>4</subscript>Cl<subscript>2</subscript> (MA<subscript>2</subscript>FeCuI<subscript>4</subscript>Cl<subscript>2</subscript>) and (CH<subscript>3</subscript>NH<subscript>3</subscript>)<subscript>2</subscript>InCuI<subscript>6</subscript> (MA<subscript>2</subscript>InCuI<subscript>6</subscript>) for the first time. We find that the device based on MA<subscript>2</subscript>InCuI<subscript>6</subscript> is highly selective for ultraviolet light (880 nA mW<superscript>−1</superscript>) and shows high anti-interference for visible-light (20–50 nA mW<superscript>−1</superscript>). The electrochemical impedance results indicate that the value (480 ± 10 Ω) of the resistance based on the MA<subscript>2</subscript>InCuI<subscript>6</subscript> photodetector device is much smaller than that (1 ± 0.001 MΩ) based on the MA<subscript>2</subscript>FeCuI<subscript>4</subscript>Cl<subscript>2</subscript> photodetector device, which in turn proves the difference in photoelectric response.
