“…The intense Yb 3 þ ion absorption lines are well suited for laser diode pumping in this range and the smaller Stokes shift between absorption and emission reduces the thermal loading of the material during laser operation [25]. These properties of the Yb 3 þ ion and the obtained emission make xerogel covalently bonded with Yb complexes very important for various photonic applications in ionic crystals and glasses [26]. Previous work has demonstrated that Yb-porphyrin complexes possess rapid rates of energy transfer from the porphyrin antennae to the acceptor Yb 3 þ ion [20][21][22][23].…”

“…However, this crystal-field splitting is lower than that in phosphates with apatite structure (about 1100 cm −1 ) [4,5,26] which are more difficult to obtain as single crystals in comparison with diphosphates NaLnP 2 O 7 (Ln = rare earth and Y).…”

“…In addition, the intense and broad Yb 3+ absorption lines are well suited for infrared (IR) InGaAs diode laser pumping, the broad emission bands allow the generation of ultra-short pulses and the small Stokes shift between absorption and emission wavelengths, leads to a low-thermal load. Among the best Yb 3+ -doped laser crystals, those of phosphates, especially with the apatite structure [1][2][3][4][5], were recognized to be favorable hosts by an evaluation of the Yb 3+ oscillator output yield [6].…”

“…Owing to the specific structure, apatite has great capacity to form solid solution and can accept several substitutes [3][4][5]. Among many synthetic apatite, the oxyapatite family are of practical interest as efficient laser-host materials and luminescence materials when doped with rare-earth ions [6,7], because of their high crystal field and excellent thermal, mechanical, and chemical properties [8].…”

A series of Ce 3+ doped Ca 8 La 2 (PO 4 ) 6 O 2 phosphors with tunable emission were successfully synthesized by traditional solid state reaction. The crystal structure and photoluminescence properties were studied through X-ray diffraction, photoluminescence excitation and emission spectra. The results indicated that Ca 8 La 2 (PO 4 ) 6 O 2 :Ce 3+ exhibited color-tunable emission due to the 5d-4f transitions of Ce 3+ ions under different wavelength excitation. The optimal doping content of Ce 3+ ions in Ca 8 La 2 (PO 4 ) 6 O 2 was found to be 5 mol%. The site-selective photoluminescence property and the reason for red-shift of the emission band along with Ce 3+ content and the excitation wavelength were also studied in detail. INTRODUCTIONIt is well known that apatite is an important family of materials with wide applications in catalysis, environmental remediation and ceramic membranes. Apatite contains a large number of inorganic compounds with the general formula M10(EO4)6X2, where M is a univalent to trivalent cation (Ca2+, Sr2+, Ba2+, Cd2+, Eu3+, Y3+, La3+, Na+, K+, etc.), E is a tetravalent to hexavalent element (P5+, V5+, As5+, Si4+, Ge4+, S6+, Cr6+, etc.), and X represents anions 2]. Apatite crystallizes in the hexagonal system with space group P63/m, which is characterized by the presence of two cationic sites labeled M(I) and M(II); the six M(II) sites are preferentially occupied by the seven coordinated trivalent ions with Cs symmetry; while the other four M(I) sites are usually occupied by bivalent ions or the remaining trivalent ions with nine coordinations and C3 symmetry, respectively. Owing to the specific structure, apatite has great capacity to form solid solution and can accept several substitutes [3][4][5]. Among many synthetic apatite, the oxyapatite family are of practical interest as efficient laser-host materials and luminescence materials when doped with rare-earth ions [6,7], because of their high crystal field and excellent thermal, mechanical, and chemical properties [8].
