DOI: 10.1002/adfm.202503202
Abstract: Photomultiplication‐type organic photodetectors (PM‐OPDs) are highly effective for detecting weak optical signals; however, achieving a balance between high gain, broad spectral sensitivity, fast response, and low operating voltage remains a significant challenge. In this study,… read more here.

DOI: 10.1038/s42004-019-0191-7
Abstract: Most solar-energy conversion applications are based on trapping and transferring photoinduced electrons on oxide semiconductor nanoparticles, such as titanium dioxide, and broad UV-vis absorption (400~800 nm) and monotonic IR absorption (1100~3000 cm−1) signals have long been considered… read more here.

DOI: 10.1039/d5mh00640f
Abstract: Enhancing photomultiplication (PM) in organic photodetectors (OPDs) requires effective control of photogenerated trapped electrons. Conventional approaches typically adjust the conduction band of the acceptor. In this study, we present a novel strategy for precisely controlling… read more here.

DOI: 10.1088/1361-6528/aaa77a
Abstract: We demonstrate that electron trapping at intrinsic precursor sites is endemic in non-glass-forming amorphous oxide films. The energy distributions of trapped electron states in ultra-pure prototype amorphous (a)-HfO2 insulator obtained from exhaustive photo-depopulation experiments demonstrate… read more here.
