Abstract
Frequency upconversion in triply ionized praseodymium doped glass with composition TeO2-Na2O (TNO) system under the excitation with a laser light from a dye laser has been reported and the covalency, bonding parameter, nephalauxetic effect which provides the information about the nature of bonding between the lanthanide ions and the surrounding oxygens for the present glassy material calculated. The energy transfer route followed by the two excited praseodymium ions is observed to be the leading process for the upconversion emission.
