Abstract
The one- and two-photon 3H4 → 3P0 excitation spectra of the 3P0 emission of Pr3+ in SrMoO4 at 4.2 K are investigated. Vibronic side bands are present in both one- and two-photon spectra. For the first time, vibronic coupling in direct 4f−4f two-photon absorption is observed. One-photon site-selective measurements are also reported.
