Three-photon absorption in Nd-doped yttrium aluminum garnet

This paper presents the results of a study of resonantly enhanced, three-, photon absorption in Nd-doped yttrium aluminum garnet (Y3Alg0~2) or Nd: YAG. The trivalent ions of the rare-earth elements, such as Nd'+, are characterized by energy levels which remain relatively sharp even in a crystalline environment, and thus crystalline solids doped with rare-earth ions present interesting systems i...

Electron-phonon coupling in iron-doped yttrium aluminum garnet

The electron-phonon coupling in iron-doped yttrium aluminum garnet crystals is studied in the theoretical framework of linear and quadratic coupling. The line shift and line broadening of the zero phonon line of iron centers as a function of temperature between 10 and 150 K is qualitatively and quantitatively explained. The spectroscopic features of the line, deduced from the theory of lattice ...

Yttrium Aluminum Garnet Fibers from Metalloorganic Precursors

Mixtures of yttrium acetate hydrate (Y(O2CCH3)3?4H2O) and aluminum formate hydrate (Al(O2CH)3?3H2O in H2O) or yttrium isobutyrate (Y[O2CCH(CH3)2]3) and aluminum isobutyrate (Al[O2CCH(CH3)2]3) in tetrahydrofuran were used as precursors to process yttrium aluminum garnet (YAG, Al5Y3O12) fibers. The pyrolytic decomposition patterns of Al(O2CH)3?3H2O, Y(O2CCH3)3?4H2O, and a [3Y(O2CCH3)3?4H2O/5Al(O2...

Effect of Synthesis Temperature on the Electrochemical Properties of Yttrium Aluminum Garnet

In this study, yttrium aluminum garnet (YAG) was prepared using a facile electrochemical technique. Four samples were synthesized in 0, 20, 40 and 60°C by electrochemical pulse deposition and were then calcined at 1200°C. The effect of synthesis temperature on morphology and structure of YAG was studied using X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron micro...
