M-C-N-O based phosphor
View Patent ↗An M-C—N—O based phosphor including a group IIIB element (M), carbon (C), nitrogen (O), wherein an amount of the group IIIB element (M) contained is 1%<(M)<50% by mass, an amount of carbon (C) contained is 0.005%<(C)<10% by mass, an amount of nitrogen (N) contained is 1%<(N)<60% by mass, an amount of oxygen (O) contained is 1%<(O)<75% by mass, and (M)+(C)+(N)+(O)=100% by mass. Colors of the M-C—N—O based phosphor can be changed by adjusting a peak top of an emission spectrum. Highly environmentally-compatible polymer dispersions, inorganic EL devices, light emitting devices, fluorescent tubes, and the like are also provided, which use the M-C—N—O based phosphors.
1. An M-C—N—O based phosphor, comprising a group 13 element (M), carbon (C), nitrogen (N), and oxygen (O), wherein
an amount of the group 13 element (M) contained is 1%<(M)<50% by mass,
an amount of carbon (C) contained is 0.005%<(C)<10% by mass,
an amount of nitrogen (N) contained is 1%<(N)<60% by mass,
an amount of oxygen (O) contained is 1%<(O)<75% by mass, and
(M)+(C)+(N)+(O)=100% by mass.
2. The M-C—N—O based phosphor of claim 1 , wherein a color changes according to an amount of carbon (C) contained.
3. The M-C—N—O based phosphor of claim 1 , wherein an amount of carbon (C) contained is 0.01-9.0% by mass.
4. The M-C—N—O based phosphor of claim 1 , wherein a peak top of an emission spectrum of the phosphor varies in a wavelength range of 300-800 nm.
