The intensity of Raman modes of four di โ erent silicate garnets in the energy range 1.9-2.7 eV was investigated. In the case of almandine and pyrope no change in intensities was observed in this (Fe 3 Al 2 Si 3 O 12 ) (Mg 3 Al 2 Si 3 O 12 ) energy region and in uvarovite a weak resonance maximum was
Abstrati-Several important applications of pure aluminium sheets (corrosion resistance, adhesion of polymer coatings, etc.) are strongly dependent upon the water content of the thin oxide layer naturally grown during processing and storage of the material. A characterization approach is presented ba
