The ZnGa2 O 4 Phosphor for Low‐Voltage Blue Cathodoluminescence
TL;DR: In this paper, the ZnCa{sub 2}O{sub 4} phosphor was investigated for its application to vacuum fluorescent displays (VFDs) utilizing lowvoltage cathodoluminescence.
Journal ArticleDOI
Defect‐Resistant Radiative Performance of m‐Plane Immiscible Al1−xInxN Epitaxial Nanostructures for Deep‐Ultraviolet and Visible Polarized Light Emitters
TL;DR: Despite the presence of high concentration of nonradiative recombination centers, the Al1-x Inx N nanostructures emit polarized light with the luminescence lifetimes of 22-32 ps at 300 K, suggesting defect-resistant radiative performance suggests supernormal localized characteristics of electron-hole pairs.
Journal ArticleDOI
