The structure and optical dispersion of the refractive index of tellurite glass
(Elsevier B.V., 2011-09-01)
The structure and optical properties of a 80TeO(2)-(20-x)Li(2)O-xTiO(2) glass system where x = 0, 5, 10, and 15 mol% has been investigated using FTIR spectroscopy and Brewster angle measurements. The sample preparation, ...
Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...
