To measure the room-temperature optical absorption tail and vacuum ultraviolet reflectivity of yttrium oxide single crystals and determine their fundamental optical constants.
Measured optical absorption in the absorption tail region and room-temperature reflectivity in the vacuum ultraviolet spectrum up to 42 eV using Y2O3 single crystals.
Calculated photon-energy-dependent optical constants via Kramers-Kronig analysis and determined Urbach rule parameters for the absorption tail.
Determined experimental Urbach rule parameters governing the optical absorption edge tail in Y2O3 single crystals.
Extracted optical constants up to 42 eV, identifying spectral fine structures tentatively attributed to transitions involving Y2+ and Y3+ free ion energy levels.
