Optical properties of an ordered array of silica nanospheres embedded with silicon nanoclusters

Journal Article · · Journal of the Optical Society of America B

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 {mu}s for {lambda}=650 to {lambda}=850nm, respectively, implying contributions from surface or interface states.
