    The correlation of blue shift of photoluminescence and morphology of silicon nanoporous by Al-Jumaili, Batool Eneaze Bandar, Talib, Zainal Abidin, Liew, Josephine Ying Chyi, Paiman, Suriati, Ahmed, Naser Mahmoud, Al-Jumaily, Abdulmajeed Hammadi Jasim, Ramizy, Asmiet, Abdulateef, Sinan A., Muh'd, Ibrahim Bagudo, Mofdal, Manahil Elnoor Edam

    Published 2015
    “…Porous silicon with diameters ranging from 6.41 to 7.12 nm were synthesized via electrochemical etching by varied anodization current density in ethanoic solutions containing aqueous hydrofluoric acid up to 65mA/cm2.The luminescence properties of the nanoporous at room temperature were analyzed via photoluminescence spectroscopy. Photoluminescence PL spectra exhibit a broad emission band in the range of 360-700 nm photon energy. …”
