(57) [Abstract] [Purpose] It emits blue light at room temperature and the emission wavelength can be easily controlled, and the size such as film thickness and shape can be easily controlled according to the function of the device. An ultrafine crystalline silicon light emitting material, a method for producing the same, an element using the ultrafine crystalline silicon light emitting material, and a method for producing the same are provided. [Structure] The ultra-fine crystalline silicon light-emitting material is composed of extremely fine ultra-fine crystalline silicon with an average grain size of about 7.5 nm or less, and it should not contain impurities or lattice defects at the boundaries between the ultra-fine crystalline silicon.
