“…These glasses find wide applications in the field of glass ceramics, layers for optoelectronic devices, thermal and mechanical sensors, reflecting windows, etc. [3][4][5][6][7][8][9]. Heavy metal oxide (HMO) glasses based on Bi 2 O 3 , PbO and Ga 2 O 3 are known to be very good candidates for producing highest refractive index among oxide glasses and an excellent infrared (IR) transmission to the longest possible wavelength.…”
