A microfabrication method is provided with which it is possible to easily form a fine periodic structure on a surface of any substrate. A glass precursor is applied to a substrate, and the glass precursor is irradiated with short-pulse laser light. By the irradiation with short-pulse laser light, the glass precursor is activated to undergo a thermal reaction, and a fine periodic structure can be easily formed on the surface. Furthermore, by oxidizing the substrate on which the fine periodic structure has been formed, the hue of the surface can be improved while maintaining the fine periodic structure.

Provided is glass containing one or more glass components selected from the group consisting of Ti ions, Nb ions, W ions, and Bi ions. The glass includes a colored layer having an arbitrary shape.

A material includes a transparent substrate on the surface of which is deposited a stack of layers which itself includes a plurality of functional layers making it possible to influence the solar and/or infrared radiation capable of striking said surface. The material has high thermal performance qualities and also an attractive shiny surface appearance of neutral color.

The present invention relates to the field of chemical industry, and discloses organosilicone micro-mesoporous ultra-low dielectric thin films and preparation methods therefor. A structural formula of a POSS-based organosilane precursor in the thin film is as follows: ##STR00001## where n is 12, 16, 18, 20, or 22, and X is CH.sub.3 or CH.sub.2CH.sub.3. The preparation method includes the following steps: dissolving a certain amount of the POSS-based precursor in an organic solvent at a room temperature; adding an appropriate amount of a photoacid generator, after uniformly stirring, spraying a mixed liquid to form a film on a substrate; placing the substrate under a light-emitting diode lamp for irradiating for a preset time after the organic solvent is completely evaporated; then placing the substrate in N,N-dimethylformamide for undergoing a transesterification reaction with fluoroalkyl alcohol for 24-72 h; and washing and drying to obtain the organosilicone micro-mesoporous ultra-low dielectric thin film. Compared with existing ultra-low dielectric thin films, the obtained thin film has a lower dielectric constant (1.89), and is better in dielectric stability in a humid environment, simple to operate, and high in polymerization speed.

Provided is a colored optical fiber of which a primary layer is easily formed. The colored optical fiber includes a bare optical fiber, a primary layer formed of an ultraviolet curing resin covering the bare optical fiber, and a secondary layer formed of an ultraviolet curing resin covering the primary layer.
