Optical and photoinduced properties of the quasi-1D metals Sr_0.95NbO_3.37 (n = 5) and SrNbO_3.45 (n = 4.5)

A comprehensive study revealed particular photoinduced features. Among others, a special laser-based mid-infrared (MIR) pump-probe reflectance setup was build. It allows room temperature transient pump-probe reflectivity experiments with fully controlled anisotropic polarizations on the sample.

Excitonic quenching of the oxygen-chain phonon in the photoinduced metal-to-insulator transition of photoexcited Sr_0.95NbO_3.37 (n = 5) studied by ultraviolet-resonance Raman scattering

This study shows that the quenching mechanism is electronically driven.
