Self-powered, filter-free, and fast solar-blind photodetectors enabled by luminescent converters with giant Stokes shift
Solar-blind photodetectors (SBPDs) are commonly plagued by trade-offs among superior spectral selectivity, high responsivity, and rapid photoresponse speed. Herein, we report a self-powered SBPD integrated with an Er3+-doped metal halide luminescent converter, nominal composition Cs2Ag0.3Na0.7In0.6Er0.4Cl6, which featu...
