Quaternary glasses with the composition 75LiBO-(15-x)BaO-10CdO-xTmO (BBLC) (0 ≤ x ≤ 2 mol %) have been prepared by melt-quenching method. The structure changes, the absorption coefficient of OH and the maximum phonon energy of these glasses are studied by FT-IR spectra. Optical and emission properties of Tm doped BBLC glasses have been investigated at room temperature.

The irradiation effect of argon, oxygen glow discharge plasma, and mercury lamp on silver and agar/silver nanoparticle samples is studied. The irradiation time dependence of the synthesized silver and agar/silver nanoparticle absorption spectra and their antibacterial effect are studied and compared. In the agar/silver nanoparticle sample, as the irradiation time of argon glow discharge plasma or mercury lamp increases, the peak intensity and the full width at half maximum, FWHM, of the surface plasmon resonance absorption band is increased, however a decrease of the peak intensity with oxygen glow plasma has been observed.
