Abstract:
Glass compositions include phosphorus oxide (P2O5), niobia (Nb2O5), barium oxide (BaO) and potassium oxide (K2O) as essential components and may optionally include titania (TiO2), calcium oxide (CaO), sodium oxide (Na2O), lithium oxide (Li2O), bismuth oxide (Bi2O3), strontium oxide (SrO), tungsten oxide (WO3) and other components. The glasses may be characterized by high refractive index at 587.56 nm at comparably low density at room temperature.
