    Spectroscopic Proprieties Of Crystals Mf2 (m=cd, Sr, Ba) Doped To Rare Earth Ions
    (University of Eloued جامعة الوادي, 2012-01-01) Diaf, M.; Khiari, S.; Labbaci, K.; Guerbous, L.; Jouart, J. P.
    In the present work, we are interested by studying the spectroscopic properties for optical applications, mainly laser amplification, of MF2 crystals, where M is an alkaline earth (Ba, Sr) or Cadmium (Cd) doped with rare earth ions (Tb3+, Er3+, Ho3+). So far, we present the absorption and emission properties and also the fluorescence dynamics at room temperature of visible and near infrared transitions of the Er3+ ion doping these matrices. We also use the formalism of Judd-Ofelt by use of absorption spectra recorded at room temperature in order to identify the spectroscopic properties inherent in all radiative transitions which can occur.
