    Strong visible photoluminescence was observed on Ge/porous silicon structure prepared by pulsed laser deposition of Ge on porous Si. The photoluminescence spectrum shows three subbands peaked at 400, 620, and 720 nm, respectively. The 400 nm peak was ascribed to GeO color centers, and the 720 nm...

    With HfO2 filled into the microcavities of the porous single-crystal silicon, the blue photoluminescence was greatly enhanced at room temperature. On one hand, HfO2 contributes to the light emission with the transitions of the defect levels for oxygen vacancy. On the other hand, the special...

    It is shown that surface treatment of porous silicon in inorganic acids and solutions of metal chlorides leads to an increase in the intensity of photoluminescence of this material. In the case of chlorides, a short-wavelength shift of the photoluminescence maximum is also observed. The effect...

    We report on the observation of persistent photoluminescence (PPL) in oxidized porous silicon. The PPL decay can be well described by a stretched-exponential function, and its decay rate is not sensitive to the change of temperature. We point out that the PPL behavior can be interpreted in terms...
