点击翻译按钮获取中文摘要

This research project aims at the molecular design and synthesis of glass-forming chiral liquid crystals(G-CLCs) with white light emission, leading to tunable laser action on the basis of the photonic band effect of G-CLCs. Such G-CLCs are prepared by utilizing energy transfer, and the gradation structure of Bragg reflection is fabricated into the highly aligned G-CLC films by super-cooling process. We will demonstrate the tunable lasing in a fully visible wavelength range through our original optical measurement system.
