The spectroscopic features of the stained glasses were examined by studying absorption, photoluminescence and electron paramagnetic resonance properties. The diffusion parameters diffusion coefficient and diffusion activation energy of silver ions were calculated based on elemental analysis data from an inductively coupled plasma ICP spectrometry, and from line scan profiles from energy dispersion X-ray analysis EDX .

Introduction Staining is a well-known method for producing coloration in glasses.1 ,2 It is usually performed by applying a silver or copper paste to glass substrates. The substrates are then heattreated at a temperature usually lower than the glass transition temperature. In the staining process, metal ions contained in the paste replace alkaline ions present on the glass surface, and migrate inside the glass, usually followed by a redox reaction of metal ions in glass andor aggregation of metal atoms.3 ,4 These metal ions, atoms or nanoparticles exhibit one or more properties of strong visible absorption, photoluminescence and nonlinear optical response.5 -11 Therefore, staining process can be used to fabricate metal-doped glasses with applications in disk optical data storage, light waveguides, microlenses and all-optical switches. Since the first step in the staining process is the same as the process known as conventional ion exchange using molten salts, it can also be used for the study of ion diffusion properties.Previously, we have conducted a systematic investigation on silver-stained soda-lime silicate glasses.12 We found that silver was heavily doped into soda-lime silicate glass by a staining process, and that the staining process was controlled by the diffusion of silver ions in glass. The incorporated silver existed in Ag , Ag 0 and Ag

“…This deep intense absorption band is observed due to the collective excitation of all the free electrons in the surface of the metal nanoparticles. The particle size of silver NPs is calculated from half width at half-maximum (HWHF) of the optical absorption peaks using Mie theory equation [21][22][23] and tabulated in Table 1. where max is the wavelength at maximum intensity of the SPR, V is the velocity of the electron at Fermi levels (1.4 × 10 6 ms −1 for silver), is the velocity of light in free space, and is the half width at half-maximum (HWHM).…”

For luminescent solar concentrators (LSCs), it is important to enhance the fluorescence quantum yield (FQY) and photostability. Our measurements have demonstrated that the addition of silver nanoparticles to dye solution causes broadening of absorption bands, so the spectral range of sunlight absorbed by LSC has increased. Silver nanoparticles (NPs) were characterized by X-ray diffraction (XRD) and UV-Vis absorption spectra. UV-Vis spectrum showed a single peak at 442 nm due to the surface plasmon resonance (SPR). The position of SPR peak exhibited a red shift after the sample was exposed to UV irradiation (unfiltered light). The optical band gap values have a reduction from 2.46 to 2.37 eV after irradiation for 960 minutes. Such reduction in optical band gap may be due to change in particle size calculated using Mie theory. The photostability of organic dyes used was improved after adding silver nanoparticles. The area under fluorescence spectra of dyes with silver NPs increased by 41-31% when compared with identical dye concentrations without silver nanoparticles as a result of interaction of the species with silver NPs.
