The 4fn↔4fn − 15d transitions of the trivalent lanthanides in halogenides and chalcogenides

The Eu3+ charge transfer energy and the relation with the band gap of compounds

Phosphors for plasma display panels

Excitation and emission characteristics were reviewed for phosphors which were reported, applied, or suggested for the plasma display panel (PDP). Correlation of luminescence characteristics to the host crystal structure and the activator of the phosphor was explained. Improvements of the PDP phosphor for the practicality were considered.

Electronic structure and optical properties of the lanthanide activated RE3(Al1−xGax)5O12 (RE=Gd, Y, Lu) garnet compounds

It is shown that Gd(BO 2 ) 2 is an excellent host lattice to obtain efficient VUV excited photoluminescent materials at room temperature. The introduction of Gd 3+ ions in the lanthanum metaborate host lattice increases both the ionicity of the metal-ligand bonding and the energy transfer rate between the host and the activator.
