• 1 nm steps over the 300–1100 nm range, and photoluminescence in the 370–800 nm range. A solid state LCS-DTL-374QT Nd:YAG 355 nm laser source (Russia) at the intensity of 19 mW/cm2 was used to excite the luminescence. Emission spectra were registered by the experimental setup described by Viter et al

• crystallites than the other one, due to the slightly different potentials applied to the two electrodes. The illumination experiments of these electrodes were carried out with a pulsed Nd:YAG laser (second harmonic, wavelength λ = 532 nm). The laser focus had a diameter of 10 µm, much smaller than the active

The spectrometer is equipped with an entrance slit of 100 µm, a focal length of 800 mm and a 300 lines/mm grating. SERS measurements were carried out by focusing the laser light onto the samples (approx
