- Abstract
4 inverse opal photonic crystals with different photonic band gaps were fabricated by template-assisted method. The 3+/3+ co-doped 4 nanoparticles were deposited on the surfaces of the inverse opals, and their up-conversion emission properties were investigated. The upconversion emissions of 3+/3+ co-doped 4 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 the inverse opals, which is attributed to an efficient and selective reflection of photonic band gaps.
