Raman and infrared spectroscopic investigation of GeO2-modified K2Si2O5 glasses synthesized by Sol–gel and standard melting methods

Two approaches for producing potassium–germanium silicate amorphous materials are presented: the conventional batch melting method followed by melt quenching, and a sol–gel synthesis route followed by melting in a furnace. Potassium disilicate glasses modified by germanium oxide...
