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.

“…The structural and optical properties of the double phosphates have been extensively studied for the last decade [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. However, sodium orthophosphates Na 3 RE(PO 4 ) 2 have been optically characterized [7, 19-21, 25, 31] mainly in its orthorhombic form.…”

“…Much study has been published about the binary orthophosphates M 3 I Ln(PO 4 ) 2 and M 3 I Ln 2 (PO 4 ) 3 (where M I = alkali metal or other monovalent metals, and Ln = a rareearth element or Y or Sc) as well as those doped with lanthanide ions (see, e.g., [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]). Information in the literature are mainly focused on the preparation methods, crystalline structure and application possibilities of those compounds.…”
