In this work, we have investigated the existence of energy transfer among Nd 3+ ions in fluoroarsenate glasses of the Na 4 As 2 O 7 , BaF 2 , YF 3 system with different Nd 3+ concentrations (0.5, 2, 3, 4, and 5 mol%) by using time-resolved fluorescence line narrowing spectroscopy. The spectral featu
