Optical and physical properties of europium doped lithium potassium borate glass

Borate glass is widely used in many scientific studies. By using melt-quenching technique five samples of lithium potassium borate (LKB) doped with different concentration of europium oxide (Eu2O3) were prepared. To investigate the influence of dopant on the optical and physical characteristics of t...
