Abstract
We first introduce the latest experimental results, i.e., production of the fine nanostructured and near fully densed transparent
Y3Al5O12 (YAG) bulks at high pressure and modest temperature (HPMT, 2.0-5.0 GPa & 300-500 oC). And then, We employ
the first-principles plane wave pseudopotential density functional theory method in the generalized gradient approximation
(GGA) to calculate the equilibrium lattice parameters, band structures, density of states, and optical properties of YAG under
high pressure. The results obtained are compared with other calculations and good agreement is found..
Keywords
High-pressure sintering, Electronic structure, Optical property, YAG.
