The invention, which belongs to the optical field, puts forward a one-dimensional photonic crystal solar blind ultraviolet band-pass filter. A quantum well structure (PC1)(PC2)(PC3)(PC4)(PC5) is formed by successive stacking of five kinds of photonic crystals PC1, PC2, PC3, PC4, and PC5 with increasing lattice constants; and the photonic crystals are formed by periodic arrangement of high-refractive-index material layers and low-refractive-index material layers. In each kind of photonic crystal, the thicknesses of the high-refractive-index material layers are equal and the thicknesses of the low-refractive-index material layers are identical. The cycle T of the photonic crystal PC1 is 6; the cycles N of the photonic crystals PC2, PC3, and PC4 are 3 to 6; and the cycle M of the photonic crystal PC5 is 6 to 10. The lattice constants are sums of the thicknesses of the high-refractive-index material layers and the thicknesses of the low-refractive-index material layers. According to the invention, the one-dimensional photonic crystal solar blind ultraviolet band-pass filter having a simple structure is capable of realizing solar blind ultraviolet-band high-efficiency filtering with the length of 240 to 280nm; and the deep cutting off of some ultraviolet and visible bands with the wavelength of 300 to 700 nm is realized. The one-dimensional photonic crystal solar blind ultraviolet band-pass filter can be applied to the field of ultraviolet filtering widely.
