AI Technical Summary

Technical Problem

MOF-based micro/nano lasers have rigid, multi-edge boundaries due to the anisotropy of crystal growth. This results in strong scattering loss at the non-smooth edge boundaries between different planes, affecting the laser output quality.

Method used

By using flexible ligands to achieve topological distortion during the growth process, amorphous spherical micro- and nano-particles are obtained, eliminating edge scattering losses. Spherical host-guest type metal-organic hybrid materials are synthesized by in-situ growth method. Isotropic growth is achieved by utilizing the distorted topological network structure of flexible ligands to form a smooth spherical surface.

Benefits of technology

It effectively eliminates edge scattering loss, improves laser output quality, and achieves laser output with high quality factor, narrow half-width, wide mode spacing, and low laser threshold.
