Abstract
Tellurite glasses are important for nonlinear optical applications. We report measurements of the spectrum of empty states in tellurium oxide, using the method of electron energy-loss spectroscopy based on excitations from inner shells. This near-edge structure is completely dominated near the threshold by core-hole effects. Several popular approximations for this effect, along with a new "Z+2" approximation, are evaluated in simulations.
