Spectral properties and charge transfer luminescence of Yb3+:Gd3Ga5O12 (Yb:GGG) crystal

Sm3+-doped (Ca,Mg,Zr)GGG crystal: A potential reddish-orange laser crystal

“…Due to the large scale demand and great advance of laser diode of about 405 nm which is used in many fields such as lighting, optical storage and also can be used to directly pump Sm 3+ -activated laser medium, the situation maybe change in the near future. Gadolinium gallium garnet (GGG) has attracted a lot of attention as a superior laser host material [9][10][11], which belongs to cubic system with the space group of O h 10 -Ia3d. (Ca, Mg, Zr)GGG is isomorphic to GGG, in which the Gd 3+ ion in the dodecahedral site is partially substituted by Ca 2+ , and the Ga 3+ ion in the octahedral site is also partially substituted by Mg 2+ and Zr 4+ ions, resulting the lattice parameters increased [12].…”

Visible luminescence in Yb3+-doped gadolinium gallium garnets

“…We have studied the emission spectra under 269, 275 and 313 nm excitations of Yb:GGG obtained at room temperature which shows that Yb:GGG cannot be suitable for scintillator applications because of the overlapping of charge transfer absorption of Yb 3+ ions with that of Gd 3+ ions [7]. Fig.…”

“…The crystal growth process was described in Ref. [7]. Samples for spectroscopic measurements were cut out of boules and the surfaces perpendicular to the growth axis were polished.…”

Preparation and properties of Nd,Yb:GGG polycrystalline nanopowders

“…6 only showed the emission of Yb 3+ , but the emission of Nd 3+ was not showed. It indicated that in the process of emission, the Nd 3+ gained energy and also transfered the energy to Yb 3+ [9,10].…”
