Abstract
Composite materials (CMs) doped with AgI or AgBr and Tb3+ or Sm3+ ions are synthesized based on matrices of high-silica nanoporous glass (NPGs). The structure of the CMs is studied by IR spectroscopy in the frequency range of 4000 to 400 cm–1. Bands corresponding to the Ag–O vibrations are found in the IR transmittance spectra of the CMs in the range of 604 to 592 cm–1. The presence of bands is established, which is associated with the existence of O–Ln–OH, Ln–O–Ln, Ln–O–H, and Ln–O (Ln = Tb, Sm) bonds compared with the NPG and series of materials without rare-earth ions (terbium or samarium). The peaks corresponding to the Ag2O and Sm2O3 oxides are found in the CMs at 940–936 and 640 and 640 cm–1, respectively.
