Controllable synthesis and formation mechanism of luminescent monodispersed NaEuF4 submicron disks through assembled nanocrystals

Monodispersed NaEuF4 submicron disks assembled from nanocrystals exhibit prominent red emission under the excitation of UV light, low-voltage electron beam, and commercial blue light-emitting diode. These disks would have potential applications in solid-state lighting, field emission displays, etc.
