The UV absorption and photoluminescence properties of phenanthroline derivatives with triphenylamine and oxadiazole groups and their europium complexes were investigated. These europium complexes display intense UV absorption and photoluminescence properties. The PL results from emission of Eu3+ ion in their pure thin films. A maximum PL wavelength is 612 nm and a full width at half maximum is from 9 nm to 15 nm for the PL of these europium complexes, respectively.
