Title (EN) NARROW-BAND RED PHOTOLUMINESCENCE MATERIALS FOR SOLID-STATE LIGHT EMITTING DEVICES AND FILAMENTS
(FR) MATÉRIAUX À PHOTOLUMINESCENCE ROUGE À BANDE ÉTROITE POUR DISPOSITIFS ÉLECTROLUMINESCENTS À SEMI-CONDUCTEURS ET FILAMENTS
Abstract:
(EN) Light emitting devices and LED-filaments comprise an excitation source (e.g. LED) and a photoluminescence material comprising a combination of a first narrow-band red photoluminescence material which generates light with a peak emission wavelength in a range 580 nm to 628 nm and a full width at half maximum emission intensity in a range 45 nm to 60 nm and a second narrow-band red photoluminescence material generates light with a peak emission wavelength in a range 628 nm to 640 nm and a full width at half maximum emission intensity in a range 5 nm to 20 nm. At least one of the first and second narrow-band red photoluminescence materials can comprise a narrow-band red phosphor or a quantum dot (QD) material.
(FR) L'invention concerne des dispositifs électroluminescents et des filaments de DEL comprenant une source d'excitation (par exemple une DEL) et un matériau photoluminescent comprenant une combinaison d'un premier matériau à photoluminescence rouge à bande étroite qui génère de la lumière présentant une longueur d'onde d'émission maximale dans une plage de 580 nm à 628 nm et une largeur totale à la demi-intensité d'émission maximale dans une plage de 45 nm à 60 nm, et d'un second matériau à photoluminescence rouge à bande étroite qui génère de la lumière présentant une longueur d'onde d'émission maximale dans une plage de 628 nm à 640 nm et une largeur totale à la demi-intensité d'émission maximale dans une plage de 5 nm à 20 nm. Au moins l'un des premier et second matériaux à photoluminescence rouge à bande étroite peut comprendre un matériau à points quantiques (QD) ou un luminophore rouge à bande étroite.
