Narrowband photodetectors conventionally rely on optical structure design orbandpass filters to achieve the narrowband regime. Recently, a strategy forfilterless narrowband photoresponse based on the charge collection narrowing(CCN) mechanism was reported. However, the CCN strategy requires an electrically and optically “thick” photoactive layer, which poses challenges in controlling the narrowband photoresponse. Here we propose a novel strategy forconstructing narrowband photodetectors by leveraging the inherent ion migration in perovskites, which we term “band modulation narrowing” (BMN). Bymanipulating the ion migration with external stimuli such as illumination,temperature, and bias voltage, we can regulate in situ the energy-band structure of perovskite photodetectors (PPDs) and hence their spectral *** the Fermi energy levels obtained by the Kelvin probe force microscopy, the internal potential profiles from solar cell capacitance simulator simulation, and the anion accumulation revealed by the transient ion-drifttechnique, we discover two critical mechanisms behind our BMN strategy: theextension of an optically active but electronically dead region proximal to the top electrode and the down-bending energy bands near the electron transportlayer. Our findings offer a case for harnessing the often-annoying ionmigration for developing advanced narrowband PPDs.

Bifidobacteriumlongumsubsp. infantis (***. infantis) and Bifidobacteriumadolescentis(B. adolescentis) play important roles in the guts of infants and adolescents， respectively. In this study， using a neonatal rat model， we compared the protective effects of these two bifidobacterial species against Salmonella infection. The results demonstrated that ***. infantis was more effective than B. adolescentis in alleviating the severity of infection in newborn rats exposed to Salmonella entericaserovarTyphimurium strain SL1344. B. *** attenuated intestinal inflammation and mucosal damage induced by Salmonella infection， as well as protecting intestinal nerves and intestinal barrier function through TLR4/MyD88 signalling. B. longumsubsp. infantis also displayed the potential to modulate gut metabolites by promoting the biosynthesis of unsaturated fatty acids (arachidonic acid， eicosapentaenoic acid and α-linolenic acid) and purine metabolism (guanine， adenine， inosine and adenosine)， thereby regulating metabolic disturbances. Additionally， the benefits of B. *** were also observed in the liver， spleen and brain， improving nerve reflexes and suppressing hepatosplenomegaly. Overall， these findings provide novel insights into the prevention and treatment of gut-related diseases in newborns， highlighting the potentially significant role of B. *** in clinical applications.
