Abstract The optical properties of Er 3+ ions in zinc borosulphate (ZnSO 4 · 7 H 2 O + B 2 O 3 ) and alkali zinc borosulphate (R 2 SO 4 + ZnSO 4 · 7H 2 O + B 2 O 3 , R 2 SO 4 = Li 2 SO 4 · H 2 O, Na 2 SO 4 , or K 2 SO 4 and Gd 2 (SO 4 ) 3 · 8H 2 O) glasses are reported. The assigned energy level data of Er 3+ (4f 11 ) in borosulphate glasses are analyzed in terms of a parametrized model Hamiltonian and in turn satisfactory eigenvalues and eigenvectors for intensity analyses are obtained. The Judd‐Ofelt theory has been applied to predict various spectroscopic parameters for the fluorescent levels of Er 3+ : borosulphate glasses and these results are compared and discussed with similar results.
