摘要：

An investigation of low-frequency inelastic scattering and fluorescence line narrowing has revealed the role of Eu3+ in the nucleation process. Analysis of the results has shown that the Eu3+ accelerates nucleation; however, it is not incorporated into the microcrystalline phase. Polarization studies have shown that the nucleating agents Eu3+ and Cr3+ modify the size of the microcrystallites and the symmetry of the vibrational eigenmodes. The results show that the vibrational eigenmodes for the Cr3+-doped glass are mainly breathing modes, whereas for the Eu3+-doped and undoped glass they are spheroidal and/or torsional modes.
