Abstract Scope Borosilicate glasses of type BK7 of composition 16 M2O – 10 B2O3 – 74 SiO2. With M = Li, Na, K, Rb, and Cs were prepared, both doped and undoped using Ni2+ prop ion. Those glasses as well as two mixed glasses with a 1:1 ratio of M = Li+Na and Cs+Rb were investigated for their structure and properties. Structural analysis of the glass was based on optical spectroscopy, Raman scattering, infrared reflectance, and nuclear magnetic resonance (NMR). NMR analysis shows that glasses containing K, Rb, and Cs have boron cations that are four-fold coordinated (BO4) tetrahedra, Raman spectroscopy saw a change in the connectivity from danburite to reedmergnerite type superstructural units. Using the probe ion Ni, a change in both color and coordination is seen as modifier ion changes, from octahedral Ni2+ (yellow) in Li-BS to tetrahedral Ni2+ (brown) with Na-BS and blue Ni3+ in higher optical basicity systems.
