Abstract

The invention relates to silica optical fiber modification, aiming at providing an ITO film loaded silica optical fiber and a preparation method thereof. The silica optical fiber is taken as base body, and indium tin oxide transparent and conductive film is coated on the surface. In the invention, simple and feasible pre-treatment is carried out on the silica optical fiber, so that ITO film obtained by sol-gel method is firmly combined with the surface of the silica optical fiber, crystallization of film is complete, surface is smooth and compact, and photoelectric properties are good, thus preparing an ITO film loaded silica optical fiber and giving both light guiding property and electrical conductivity to the fiber. The invention can be widely applied to the fields of infrared transmission, current sending and photoelectric response devices, thus greatly widening respective application field.

Description

technical field [0001] The invention relates to the modification of quartz optical fiber, in particular to a method for coating the surface of the quartz optical fiber with an ITO thin film with strong binding force and good photoelectric performance. Background technique [0002] Tin-doped indium oxide (Indium Tin Oxide, abbreviated as ITO) transparent conductive film, as an n-type degenerate semiconductor, is known for its good electrical conductivity, high transmittance in the visible range and reflection in the infrared range High efficiency, good binding ability with the matrix and good chemical stability have attracted more and more attention, and have been used in many fields including flat display (liquid crystal display LCD, organic electroluminescence display OLED), solar cells, sensors, functional glass etc. are widely used. [0003] Quartz Optical Fiber (QOF for short) has a series of advantages such as anti-electromagnetic interference, good confidentiality, an...
