    Abstract

    The photoluminescence involving transitions from the ground to 4fn-15d1 states were studied using excimer lasers or synchrotron radiations. Temperature dependence of the photoluminescence was also considered. Five kinds of Er3+-doped pure silica and ZBLAN glasses were employed. The optical absorption due to the 4f105d1 structure of Er3+ was noted using synchrotron radiation. In addition, the intensities of luminescence bands from two neighboring luminescence states were found to depend inversely on the measuring temperature. This was justified by assuming that electrons are in thermal equilibrium between the two states.
