Judd–Ofelt analysis and near infrared emission properties of the Er3+ ions in tellurite glasses containing WO3 and CdO

The influence of erbium (Er3+) ion concentration on the infrared emission at 1.5?m in TeO2?WO3 and TeO2?CdO?WO3 glasses was studied. The samples were prepared by conventional melt quenching method.

Synthesis, visible light absorption and luminescence of bipyrimidine bridged dinuclear lanthanide complexes of 2,4-pantanedione

Each lanthanide ion is eight-coordinate, in these dinuclear complexes, and is bound to six-O atoms of acac and two N-atoms of bridging bipyrimidine. The purity and homodinuclear nature of the complexes have been established by elemental analysis, NMR, and 4f?4f absorption spectroscopy.
