Stable photoluminescence (PL) was achieved in iron-passivated porous silicon (IPS). The PL spectra of IPS and normal porous silicon were fitted by the method of Yorikawa and Muramatsu [Appl. Phys. Lett. 71, 644 (1997)], based on a statistical distribution of particle size. The fitting results indicate that the unchanged size distribution of Si nanocrystallites results in the nonblueshift PL in IPS with time. The quantum confinement model is strongly supported by our experiments and analyses.

During the commissioning of RPC detector systems at the Daya Bay Reactor Neutrino Experiment, calibration algorithms were developed and tuned, in order to evaluate and optimize the performance of the RPC detectors. Based on a description of the hardware structure of the RPC detector systems, this paper introduces the algorithms used for detector calibration, including trigger rate, efficiency, noise rate, purity and muon flux.
