Optoacoustic characterization of synthetic opals
The development of laser-based ultrafast acoustic techniques allowed the investigation of the vibrations of nanostructures. In this communication, we report the results of the characterization of crystals composed of silica nanospheres (opals) by pump-probe setup. In our study, the excitation and de...

Summary: | The development of laser-based ultrafast acoustic techniques allowed the investigation of the vibrations of nanostructures. In this communication, we report the results of the characterization of crystals composed of silica nanospheres (opals) by pump-probe setup. In our study, the excitation and detection of the vibrations of nanospheres by femtosecond laser pulses was facilitated by filling the pores in the opals by GaAs semiconducting material. |
