Abstract

The different mechanisms of photoluminescence (PL) of silicon nanocrystals due to quantum confinement effect (QCE) and interface states were studied. Si nanocrystals were formed by pulsed-laser deposition in inert argon and reactive oxygen gas. The PL band at 2.55 eV showed vibronic structures with periodic spacing of 97±9 meV.
