A study was conducted to demonstrate a broad and tunable visible-light emission, excited by electrons from europium (Eu)-doped boron nitride nanotubes (BNNT). The BN nanotubes served as the host and contributed directly to the light emission. In situ Eu doping was used to incorporate Eu atoms between BN nanotube walls. Pure Eu-doped nanotubes were analyzed, using cathodoluminescent panchromatic imaging and spectroscopy attached to a scanning electron microscope (SEM). The pure nanotube samples...[Show more]
