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 …
