Yb3+/Er3+ co-doped NaYF4 nanoparticles were deposited on the surfaces of the inverse opals, and their up …-conversion emission properties were investigated. The upconversion emissions of Yb3+/Er3+ co-doped NaYF4 nanoparticles on the inverse opal … surfaces have been enhanced when the upconversion emission bands of the nanoparticles are in the range of photonic band gaps of …

We report a numerical simulation of the conduction and valence band edges of Cd<Subscript>1-x</Subscript>Zn<Subscript>x</Subscript>S nanocrystallites using a one — dimensional potential model. Electron — hole pairs are assumed to be confined in nanospheres of finite barrier heights. Optical absorption measurements are used to fit the...</subscript></subscript>
