UV-VIS-NIR spectral optical properties of silver iodide borate glasses

We present a study of optical properties of a series of silver iodide borate glasses(AgI)x(Ag2O·B2O3)1−xby UV-VIS-NIR spectroscopy. The results show an increased absorbance in the whole analysed spectral range when the AgI concentration is augmented. In particular, the enhanced intensity of the wavelength band at 400–500 nm with silver iodine content suggests that this band arises from plasmon-related absorption, describing the formation of silver nanoparticles. With respect to this study, our results could motivate novel target designs consisting of ternary silver boron based bulk glasses for generating resonant absorption of laser light by plasma.
