In this work, due to the challenge for improving the efficiency of photonic materials actived by Rare Earth ions (RE), Tin dioxide (SnO2) nanocrystals based glass ceramic was employed and it was proved as a viable photonic material. The base material for doping RE ions was formed by embedding Tin dioxide nanocrystals into silica. The properties of the material were investigated by both simulations...
We demonstrate an easy and scalable way to get devices in which the electrical resistance can be tuned by UV/visible light exposure. In particular, such a feature is based on photochromic diarylethene polymer - carbon nanotubes blend where reversible light controlled switching of the photochromic component induces a change in the electrical conductivity of the material. Differently from the single...
Sub-10-fs visible pulses allow real time detection of coherent phonons in single-walled carbon nanotubes. Nonlinear coupling between radial breathing (250 cm-1) and the carbon-stretching (1600 cm-1) modes is experimentally observed and theoretically modeled.
