Optical and dielectric behaviors of alumina after an electromagnetic irradiation
Source abstract
Abstract
Abstract During an electromagnetic irradiation (UV), the coloration of α-Al 2 O 3 material is modified. With cathodoluminescent experiments, specification of the electronic rearrangement which is induced by the UV irradiation has been tried. The quantity of electrical charges which can be trapped in the sapphire to determine how the electronic state of the structural defects can modify the trapping capacity has also been measured.
