Abstract

The invention discloses a method for preparing a neodymium oxide-doped composite thin film material. Neodymium oxide nanocrystals are prepared by an improved microemulsion method, and are mixed into a titanium dioxide-based composite film using sol-gel technology combined with low-temperature organic-inorganic composite technology. In the organic-inorganic composite material, the organic photosensitive functional group is finally introduced, and a titanium dioxide-based organic-inorganic composite optical waveguide material with both upconversion luminescence function and photocuring function and excellent optical waveguide performance is prepared. The composite thin film and strip waveguide array of the present invention can excite an obvious strong bright blue up-conversion luminescence with a wavelength of 436nm under the excitation of green light with a wavelength of 580nm. The preparation process is simple, the production cost is low, and mass production can be realized. The composite thin film and strip optical waveguide array have photocuring function, and have very important applications in the fields of photonics and optoelectronic device preparation.

Description

technical field [0001] The invention relates to the preparation of an organic-inorganic composite film material, in particular to a preparation method of a neodymium oxide-doped composite film material. Background technique [0002] Ultrafine monodisperse nanoparticles have broad applications in the fields of lasers, magnetic particles, semiconductors, superconductors, and metal catalysts due to their unique physical properties, such as size quantization, nonlinear optical behavior, and anomalous fluorescence. 4) It has novel optical and transmission properties and potential application value. Their optical transitions can be tuned by changing the size of the clusters. In addition, in recent years, the conversion of yellow light to violet light by Nd-doped optical materials has been extensively studied, which has a wide range of applications in the fields of color display, optical data storage, sensors, and optical communication. However, the rare earth doped glass prepare...
