[EN] Nd3+-doped RE3Ga5O12 (RE = Gd, Y, and Lu) nano-crystalline
garnets of 40-45 nm in size have been synthesized by a sol-gel method.
With the decrease of the RE atom size, the chemical pressure related to the
decreasing ...
This work reports an experimental and theoretical lattice dynamics study of
nanocrystalline Y3Ga5O12 (YGG) garnet at high pressures. Raman scattering measurements in
nanocrystalline Tm3+-doped YGG garnet performed up to ...

A structural transformation from the zircon-type structure to an amorphous phase has been found in YVO4:Eu3+ nanoboxes at high pressures above 12.7 GPa by means of x-ray diffraction measurements. However, the pair distribution ...
[EN] The structural and vibrational properties of nanocrystalline yttrium orthoaluminate perovskite (YAlO3) under compression have been experimentally studied. Experimental results have been compared to ab initio simulations ...
