  • Impact of Chemical Doping on Optical Responses in Bismuthdoped

    Nov 13, 2017 Based on the timeresolved PL measurements, we attribute the PL response to a shorter carrier lifetime induced by Bi doping, which results in a reduced photon recycling effect (i.e., the repeated emission and reabsorption of photons inside the crystal). We discuss the physical relation between Bi
