Calcium boro fluoro zinc phosphate glasses modified using alkali oxide and doped with Nd 3+ and Er 3+ ions with the chemical composition of 69.5 (B 2 O 3 ) + 10 (P 2 O 5 ) + 10 (CaF 2 ) + 5 (ZnO) + 5 (Na 2 O/Li 2 O/K 2 O) + 0.5 (Er 2 O 3 /Nd 2 O 3 ) were prepared using a conventional melt quenching technique. The results of X-ray diffraction patterns indicated the amorphous nature of all the prepared glasses. The visible-near-infrared red (NIR) absorption spectra of these glasses were analyzed systematically. The NIR emission spectra of Er 3+ and Nd 3+ :calcium boro fluoro zinc phosphate glasses showed prominent emission bands at 1536 nm ( 4 I 13/2 → 4 I 15/2 ) and 1069 nm ( 4 F 3/2 → 4 I 11/2 ) respectively with λ exci = 514.5 nm (Ar + laser) as the excitation source.
