Abstract

The optical properties of Si nanoclusters embedded within an ordered array of silica spheres have been measured. Raman data were used to confirm the existence of the Si nanoclusters. Reflection measurements and a large photoluminescence signal demonstrated the effect of the periodic structure on the optical characteristics. The wavelength-dependent, photoluminescence decay time was in the range of 7 to 24 μs for λ. = 650 to λ = 850 nm, respectively, implying contributions from surface or interface states.
