Problems solved by technology

[0004] The self-assembly method can be used to prepare a three-dimensional porous structure, but it can only prepare a periodic structure, and cannot prepare a photonic amorphous with only a short program and a lack of a long program. The phase separation method can also be used to prepare a three-dimensional porous structure. However, It produces holes that are too large to match wavelengths in the visible range
[0005] The present invention solves the problem of SnO in the visible light range of the above-mentioned prior art 2 Due to the difficulties in the preparation of photonic amorphous crystals and the inability to prepare photonic amorphous crystals with only a short program, a method of filling templates by sol-gel method and then removing templates at high temperature to obtain SnO 2 A method for preparing a three-dimensional porous photonic amorphous semiconductor material, which has the beneficial effects of easy acquisition of templates, simple method, low cost, and high repeatability

Technical field [0001] The invention involves the field of photon crystals, semiconductor materials and device technology, and specifically involves a SNO 2 Three -dimensional multi -pores of non -crystalline non -crystal semiconductor materials and their preparation methods. Background technique [0002] Many bird feathers in nature have natural structural colors. This color comes from the periodic structure inside the feather, not pigment in feathers.For photon crystals composed of periodic structures, they have been widely studied due to their unique light transmission characteristics.And another photon non -crystal material, especially the photon non -crystal that work in the visible light range, also has its unique photogenic transmission phenomenon, such as the localization and random laser of photon.With only short programs and lack of long programs.At present, the methods of preparation of porous structures include self -assembly methods and division methods. None of them...
