Abstract: front page image
(EN) A method of forming an optical device includes providing an optical element, providing a luminescent suspension including a liquid encapsulant material, phosphor particles, a solvent and a thixotropic agent, atomizing the luminescent suspension, and spraying the atomized luminescent suspension onto the optical element using a flow of pressurized gas. A light emitting structure includes an optical element configured to emit light upon energization thereof, and a thin phosphor layer including a thixotropic agent on the optical element.
(FR) L'invention concerne un procédé de formation d'un dispositif optique comprenant l'obtention d'un élément optique, l'obtention d'une suspension luminescente comprenant un matériau d'encapsulation liquide, des particules de luminophore, un solvant et un agent thixotrope, l'atomisation de la suspension luminescente, et la pulvérisation de la suspension luminescente atomisée sur l'élément optique au moyen d'un flux de gaz sous pression. Une structure électroluminescente comprend un élément optique configuré pour émettre de la lumière lorsqu'on l'excite, et une mince couche de luminophore comprenant un agent thixotrope sur l'élément optique.
