Abstract:
(EN) A silicon-based oxynitride cyan phosphor with enhanced fluorescence and a preparation method therefor, relating to the technical field of luminescent materials, and resolving the issue of insufficiently high fluorescence brightness of BaSi2O2N2:Eu2+ oxynitrides in the prior art. The phosphor of the present invention has a chemical formula of (Bal-x-y-z-mMxRyAz)O·0.5SiO2·0.5Si3N4:mEu2+, wherein 0.01≤ m ≤ 0.05, 0 ≤ x ≤ 0.2, 0.005 ≤ y ≤ 0.2, 0.5 ≤ y / z ≤ 1, and 0 < x + y + z < 0.5; R is at least one of La, Y, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, Pr, and Mn; M is at least one of Ca, Sr, and Mg; A is at least one of K, Na, and Li. The phosphor has high fluorescence intensity and an excitation peak thereof is stable within 490-500 nm when excited by blue light.
(FR) L'invention concerne un luminophore cyan d'oxynitrure à base de silicium à fluorescence accrue et un procédé de préparation s'y rapportant, se rapportant au domaine technique des matériaux luminescents et permettant de résoudre le problème de luminance de fluorescence insuffisamment élevée d'oxynitrures de BaSi2O2N2:Eu2+ selon l'état antérieur de la technique. Le luminophore selon la présente invention a une formule chimique (Bal-x-y-z-mMxRyAz)O·0,5SiO2·0,5Si3N4:mEu2+, dans laquelle 0,01 ≤ m ≤ 0,05, 0 ≤ x ≤ 0,2, 0,005 ≤ y ≤ 0,2, 0,5 ≤ y/z ≤ 1 et 0 ≤ x + y + z ≤ 0,5 ; R représente au moins l'un de La, Y, Tb, Dy, Ho, Er, Tm, Yb, Lu, Bi, Pr et Mn ; M représente au l'un de Ca, Sr et Mg ; et A représente au moins l'un de K, Na et Li. Le luminophore a une intensité de fluorescence élevée et un pic d'excitation de celui-ci est stable dans la plage de 490-500 nm lorsqu'il est excité par de la lumière bleue.
