We report the optical properties of Y3Al5O12 (YAG) crystal doped with Ho3+ ions. Absorption, emission, and lifetime measurements have been performed and discussed using Judd–Ofelt theory. Visible emissions from the 3D3 (at about 33 000 cm−1), 5S2 (18 500 cm−1) and 5F5 (15 500 cm−1) excited states and IR emissions from the 5I6 level have been characterized under pulsed one-photon excitation and the experimental lifetimes for these levels have been compared with those obtained theoretically by using Judd–Ofelt approach. Upconversion processes for achieving blue and green fluorescence under one-color red and IR have been investigated.
