Upconversion Process

This paper report, the structural and spectroscopic properties of Gd2O3 nano-phosphor activated with Ho3+ ions. XRD, SEM and TEM techniques have been used for the structural characterizations. The phosphor contains spherical nanocrystallites with uniform size of ~40 nm. Enhanced IR to green and red photon avalanche upconversion is reported under 976 nm laser excitations. Further, annealing shows a significant improvement in emission intensity. Temporal evolution of upconversion emission intensity were measured which suggests the photon-avalanche mechanism is responsible for the upconversion process. The enhancement of emission was explained and the photo-physics involved is correlated with the unique structural properties of the crystallites formed.
