CA 2592096

A light emitting device can include a substrate, electrodes provided on the substrate, a light emitting diode configured to emit light, the light emitting diode being provided on one of the electrodes, phosphors configured to change a wavelength of the light, and an electrically conductive device configured to connect the light emitting diode with another of the plurality of electrodes. T he phosphors can substantially cove at least a portion of the light emitting diode. The phosphor may include aluminate type compounds, lead and/or copper doped silicates, lead and/or copper doped antimonates, lead and/or copper doped germanates, lead and/or copper doped germanate-silicates, lead and/or copper doped phosphates, or any combination thereof.

Dispositif électroluminescent pouvant comprendre un substrat, des électrodes disposées sur le substrat, une diode électroluminescente configurée pour émettre de la lumière, la diode électroluminescente étant disposée sur une des électrodes, des luminophores configurés pour changer une longueur d'onde de la lumière et un dispositif conducteur électriquement configuré pour connecter la diode électroluminescente avec une autre de la pluralité d'électrodes. Les luminophores peuvent pratiquement recouvrir au moins une partie de la diode électroluminescente. Le luminophore peut comprendre des composés de type aluminate, des silicates dopés au cuivre et/ou au plomb, des antimoniates dopés au cuivre et/ou au plomb, des germanates dopés au cuivre et/ou au plomb, des germanates-silicates dopés au cuivre et/ou au plomb, des phosphates dopés au cuivre et/ou au plomb ou toute combinaison de ceux-ci.
