Concentration dependence of spectroscopic properties and energy transfer analysis of the fluorophosphate glasses with small phosphates content doped with Nd3+ ions
Source abstract
Abstract
Abstract A series of new fluorophosphate glasses with small content of phosphates doped with various Nd3+ ions concentration for optical applications has been prepared and characterized. Based on Judd-Ofelt intensity parameters, radiative transition probability, radiative lifetime, branching ratio, and emission cross-section of Nd3+ions have been derived for all Nd3+concentrations.The effect of the glass rigidity and lead presence in glass composition on radiative properties have been estimated. The high emission cross-section (2.33×10−20 cm2) and large quantum efficiency (93%) both suggest the glass potential for compact 1.06-μm laser applications. The analysis of luminescence kinetics has shown the formation of neodymium ion clusters beginning from neodymium concentration of 1.006 × 1020 cm−3.
