PHOSPHOR AND LIGHT-EMITTING DEVICE USING SAME

A phosphor containing a luminescent center and light-absorbing ions in a matrix. The light-absorbing ions have a wavelength range over which fluorescent components emitted by the luminescent center can be partially absorbed and have a light-emitting spectrum that has a depression over said wavelengt...

More Information
Summary:A phosphor containing a luminescent center and light-absorbing ions in a matrix. The light-absorbing ions have a wavelength range over which fluorescent components emitted by the luminescent center can be partially absorbed and have a light-emitting spectrum that has a depression over said wavelength range. Light emission that is color controlled and that has a desired and specific light-emitting spectrum shape can thereby be achieved, even without using a member that has an optical filtering function. La présente invention concerne un phosphore contenant un centre luminogène et des ions photo-absorbants dans une matrice. Les ions photo-absorbants possèdent une plage de longueurs d'onde sur laquelle les composants fluorescents émis par le centre luminogène peuvent être partiellement absorbés et possèdent un spectre électroluminescent qui présente une dépression sur ladite plage de longueurs d'onde. Une électroluminescence contrôlée par la lumière et qui présente une forme de spectre électroluminescent souhaitée et spécifique peut donc être obtenue, même sans utiliser un élément qui possède une fonction de filtre optique.
