Luminescent Er 3+ doped transparent alumina ceramics [PDF]
Abstract We report on successful preparation of Er3+ doped transparent alumina (0.1–0.17 at.%) exhibiting visible light photoluminescence using wet shaping method and hot isostatic pressing. The effects of dopant amount, type of doping powder and powder pre-treatment on final microstructure, real in-line transmittance and photoluminescence ...
