Enhancement of the blue photoluminescence intensity for the porous silicon with HfO(2) filling into microcavities
With HfO(2) filled into the microcavities of the porous single-crystal silicon, the blue photoluminescence was greatly enhanced at room temperature. On one hand, HfO(2) contributes to the light emission with the transitions of the defect levels for oxygen vacancy. On the other hand, the special fill...
