Abstract
An EL element and a laser luminescent element capable of emitting ultraviolet ray with high wave length purity. The ultraviolet electroluminescent element characterized in that: a thin film made from one of polymer and oligomer in which elements selected from Si, Ge, Sn, and Pb are directly bonded; the elements are selected from those that are the same with each other and those that are different from each other; the film is disposed between two electrodes; and at least one of the electrodes is transparent. The laser luminescent element characterized in that: a thin film made from one of polymer and oligomer in which elements selected from Si, Ge, Sn, and Pb are directly bonded is disposed between two electrodes; and the elements are selected from those that are the same with each other and those that are different from each other.
