Synthesis and characterization of Nd3+-Yb3+ doped hydroxyapatite nanoparticles

The present work focuses on Nd3+-Yb3+ co-doping of bare and Sr-substituted hydroxyapatite nanoparticles and their chemical, structural and optical characterization. An energy transfer between Nd3+ and Yb3+ centers was found, generating an efficient down-shifting process, where Nd3+ absorbs at a low...
