Infrared spectroscopy of cluster ions: High energy conformer trapping and multiple photon absorption
… tagged hydrated alkali metal ion clusters, multiple photon absorption processes can occur. The cluster ions discussed in this dissertation are generated by impacting neutral clusters with ions. If there is an energetic barrier between the neutral cluster configuration and the global minimum …

Metal oxides for efficient infrared to visible upconversion
… Several mechanisms are involved, including multiple photon absorption and energy transfers between dopants. Up to now, reported upconversion efficiencies have been relatively low, excitation thresholds quite high, and the investigated phosphors (generally fluorides) often presented poor …
