  • Publication number: 20210310072
    Abstract: A method of screening a skin whitening agent uses the stromal cell-derived factor 1 (SDF1) promoter region, the correlation between the expression amount of the skin pigment and the expression of the SDF1 promoter is observed and thus it is expected to be available in systems for pre-screening pigmentation substances and pigment reduction materials, and the drugs screened by the method is used for treatment of skin pigment-related diseases.

  • Patent number: 10150912
    Abstract: There is provided a red phosphor that may include a nitride represented by a formula of (Sr1-x-yBaxEuy)2Si5N8, wherein 0<x<0.7, and 0<y<0.1. The red phosphor may emit light having a peak wavelength in a range of 600 nm to 630 nm when irradiated by an excitation source and the excitation source may be a blue light source having a dominant wavelength in a range of 420 nm to 470 nm.

  • Patent number: 10002992
    Abstract: A red phosphor contains a nitride having a formula of SrxMgySizN2/3(x+y+2z+w):Euw, in which x, y, z, and w satisfy the relationships 0.5?x?2, 2.5?y?3.5, 0.5?z?1.5 and 0<w?0.1. The red phosphor is configured to emit light having a peak wavelength in a range of from 610 nm to 625 nm when irradiated by an excitation source, and the excitation source may be a blue light source having a dominant wavelength in a range of 420 nm to 470 nm. In such a case, the spectrum of the emitted light has a full-width at half-maximum (FWHM) less than or equal to 55 nm.
