Hybrid halide perovskites materials have the potential for both photovoltaic and light-emitting devices. Relatively little has been reported on the kinetics of charge relaxation upon intense excitation. In order to evaluate the illumination power density dependence on the charge recombination mechanism. we have applied a femtosecond transient mid-IR absorption spectroscopy with strong... https://medicalwarehouses.shop/product-category/first-aid/
