Spectroscopic features of erbium-doped CaM2O6 (M=Nb, Ta) single crystal fibers grown by the laser-heated pedestal growth technique

The Synthesis, Properties, and Applications of Columbite Niobates (M2+Nb2O6): A Critical Review

“…de Camargo et al 127 also studied high optical quality Er 3+ ‐doped CaNb 2 O 6 single crystal fibers with 700 μm diameter and 1–2 cm length, grown by the LHPG technique. Successful incorporation of the dopant ions gave a light pink coloration, and intense emission was observed at 1550 nm.…”

Arrays of micro-cavities activated with laser ions

“…Instead, the presence of Er 3 + ions that diffused from the CaTiO 3 filled voids are present into the annular boundary compound. The confocal fluorescence spectrum of Er 3 + ions in the nanocrystals is compared to that of Er 3 + ions in the ring-shaped compound confirming the presence of Er 3 + ions into the CaNb 2 O 6 structure [9]. The confocal fluorescence map collecting the emission Er 3 + in CaNb 2 O 6 is depicted in Fig.…”

Structural and optical properties of Ta2O5:Eu3+: Mg2+ or Ca2+ phosphor prepared by molten salt method

“…[3][4][5].In recent years, transparent wide band gap oxides have been doped mainly to tune desirable properties for optical and electroptical applications [6]. In addition rare earth metals provide 4f n transitions showing high luminescence efficiency doped in several hosts lattices [7][8][9] for solid state laser applications [10]. The tantalum (V) oxide (Ta 2 O 5 ) has potential as a host material for new phosphors due to its low photon energy (100 -450 cm -1 ) [11].…”
