Construction of organic micro/nanocrystal lasers: from molecules to devices

The rapid development of integrated circuits from the electron tube to the transistor has made the electronic components in integrated circuits develop towards miniaturization, which results in the growing demand for micro/nanoscale solid-state lasers. Organic semiconductor materials are vital in various optoelectronic devices, such as field effect transistors, light-emitting diodes, and optical waveguides. Especially, the solid-state laser behavior of organic micro/nanocrystals relying on intermolecular interactions are expected to be promising candidates in constructing novel miniaturized electronics due to their adjustable physicochemical properties, tunable optical performance, and the built-in cavity for optical confinement. However, there are still many difficulties to overcome before organic crystals are actually served as components in integrated circuits. Herein, we summarize and look forward to the future development directions of organic micro/nanocrystal lasers.
