Embodiment 1

[0033] A method for preparing a perovskite microring resonator array, by adding perovskite MAPbBr 3 The precursor solution is confined between the template and the substrate, and the evaporation of the solvent is promoted by heating, so that the solution shrinks to the junction of the template micro-column structure and the substrate, forming a ring of high-concentration precursor solution around the micro-column. When the concentration reaches a After a certain value, crystallization begins around the micro-column to form a ring-shaped crystal, and the micro-ring resonator array conforming to the structure of the template is obtained after the template is removed.

Abstract

The invention discloses a perovskite micro-ring resonator array, a preparation method and application thereof. The invention belongs to the technical field of perovskite crystal patterning. The preparation method comprises: limiting an organic-inorganic hybrid perovskite MAPbBr<3> precursor solution in the middle of a template with a microstructure; and the perovskite crystal is nucleated and crystallized along the edge of the microstructure of the protruding part on the template through heating, the template is removed after crystallization is completed, and finally the MAPbBr<3> micro-ring resonator array is prepared. According to the main principle, the crystallization process is controlled at the edge of a micro-column by utilizing the induction effect of the edge of a micro-column structure protruding out of a template on crystallization, and finally the micro-ring resonator array with the shape consistent with the shape and size of the structure of the template micro-column arrayis obtained.

Description

technical field [0001] The invention belongs to the technical field of perovskite crystal patterning, and in particular relates to a perovskite microring resonator array, a preparation method and an application thereof. Background technique [0002] In recent years, the development of optoelectronic information technology requires the integration of optoelectronic devices to be higher and higher. Therefore, due to its compact structure, high integration and rich functions, microring resonators are widely used as the basic construction of photonic integrated systems. one of the elements. Although in other material systems, the preparation process of microrings is very mature and simple, in the perovskite material system, due to its inherent crystallization tendency, microring resonators are difficult to realize. At present, the main preparation method of perovskite microring resonators is to control the crystal shape through polystyrene spheres. However, this method faces d...
