Dynamic Light Scattering in Phosphate Glasses
Phosphate glasses have been used in various technological applications. There have been legitimate literatures by experiments showing the structural properties of the phosphate glasses. There are several kinds of phosphate glasses that depend on the ratio of their bridging oxygen, from network of phosphorus pentoxide-P2O5, to chain of metaphosphate-MPO3. Recently, the condensed matter group of Creighton University studied two kinds of phosphate glasses: P2O5 and the metaphosphate. As are desire to continue to study the unusual behavior of phosphate glasses, we prepare ultraphosphate glasses solution of different composition as point to understand further the dynamics of the molecules shifting from the network of P2O5 to a polymer chain of metaphosphate.
