On the use of dynamical diffraction theory to refine crystal structure from electron diffraction data: application to KLa5O5(VO4)2, a material with promising luminescent properties

A new lanthanum oxide, KLa5O5(VO4)2, was synthesized using a flux growth technique that involved solid-state reaction under an air atmosphere at 900 degrees C. The crystal structure was solved and refined using an innovative approach recentl...
