摘要	The Mo-doped titania exhibits a visible broadband emission under a 978 nm laser diode excitation. The luminescence has been assigned to the transitions from the excited states T-3(1), T-3(2) to the ground state (1)A(1) of the [MoO4](2-) radical. In TiO2:Mo system, the power dependence of the upconversion-luminescence intensity exceeds a quadratic dependence, and the time evolution of the upconversion luminescence after the onset of continuous wave excitation is characterized by a rise time of 63 ms. These properties show the typical fingerprints of a photon avalanche. No luminescence was observed from the sample when excited with a pulsed laser (1064 nm) from a Nd:YAG or a pulsed Raman-shift laser (953.6nm) pumped by a second harmonic of the Nd: YAG. Regardless of the energy mismatch between the pulsed laser and the continuous wave diode laser, another reason may be that the duration time of a single laser pulse (10 ns) is much shorter than the rise time of the photon avalanche. The fluorescence "transfer function" theory is used to study the luminescence dynamics, which provides a good description of the experimental data.
