A tutorial introduction to the spectra of lanthanide ions is given. The chapter begins with a brief comparison of luminescence of lanthanide ions (Ln 3+ ) in the solid, liquid, and gas phases. Then a description of the importance of nonradiative versus radiative processes is made. The various types of transition of lanthanide ions encountered are then introduced: 4f N -4f N ; 4f N -4f NÀ1 5d; charge transfer; host band-to-band; and defect site or impurity transitions. Reference is briefly made to the spectra of dipositive ions. The luminescence of lanthanide ions in non-lanthanide hosts is examined, and the importance of locating the relative positions of Ln 3+ energy levels relative to the host band gap is stressed. Some of the various upconversion phenomena, including second harmonic generation, twophoton absorption, ground state/excited state absorption, energy transfer upconversion, and photon avalanche, are then described with reference to Ln 3+ and Ln 3+ -TM n+ (transition metal) systems. The experimental distinctions of which particular process is operative in a given system are explained by considering the power, concentration, and lifetime dependences, and the upconversion excitation spectrum. Some applications of lanthanide luminescence are briefly reviewed and a mention of the luminescence in nanomaterials is also included.

This paper describes a computational study of extrinsic defect and optical properties of SrAl 12 O 19 induced by trivalent rare earth dopants. Solution energies for a range of possible doping mechanisms are calculated, and predictions made of doping sites and chargecompensation schemes. Atomistic modelling is used to calculate the symmetry and detailed geometry of the dopant ion-host lattice system, and this information is then used to calculate the crystal field parameters. It is found that the preferred doping mechanism for Pr is a substitution
