The initial luminescence of crystals is greatly reduced after introduction of noble ions. The luminescence of noble ions quenches at 700K without drop in intensity at 200K. For luminescence associated with silver the energy of thermal quenching is 0.7±0.1eV with a frequency coefficient of 1 · ...

The frequency change due to the adsorption of hexanethiol molecules onto the ZnO nanorod-coated quartz crystal was 10 times that observed using a quartz crystal coated with a plain ZnO film, due to the higher surface area of the nanorods compared to the film. UV irradiation of the nanorod-...
