| Abstract Scope |
Selected glass chemistries, 75 wt% B2O3 and 25 wt% Na2CO3, as well as clear Moretti art glass, were used for the study. A series of set of dopants (for example, neodymium and praseodymium) was tested for ranges of colors, keeping the art glass industry in mind. The base glasses were mixed with the sets of dopants and remelted above 1100°C under ambient atmosphere for about 1 h and quenched by pouring on a graphite surface. The samples were polished into small disks of approximate dimensions of 1 mm thick and 5 mm diameter for characterization. UV-Vis-NIR, Raman, and FTIR spectroscopic techniques were used to characterize the optical and structural properties of the glasses. This dichroism and its stability in these glasses were studied in terms of colloids/nanocrystals formed. |
