We investigate the optical properties and surface-enhanced Raman scattering (SERS)
characteristics of metal-coated silica aerogels. Silica aerogels were fabricated by easily …

Noble metal surface plasmon resonance or photonic crystals (PCs) effect is a novel and
effective method for improving upconversion luminescence (UCL). UCL can be effected by …

Optically transparent MgAl 2 O 4 ceramics was functionalized by Cu 2+-ions employing
various implantation fluences. Depending on ion beam exposure, both radiation stimulated …

Photon upconversion (UC) is the sequential absorption of two or more low frequency
photons and subsequent emission of light at a higher frequency. Because of a large number …
