Abstract:
In this paper the Stark components of 4S(3/2), 2H(11/2) and 4I(15/2) levels of Er3+ ion doped in oxyfluoroborate glass have been resolved using laser excitation and fluorescence measurements. The lifetime of 4S(3/2) level as a function of Er3+ concentration in the glass host has also been measured. Concentration quenching due to interaction among rare earth ions and the mechanism responsible for the same has been elucidated. The Judd-Ofelt analysis of the absorption spectrum has also been carried out.
