Liquid Crystals: Thermally and Electrically Tunable Lasing Emission and Amplified Spontaneous Emission in a Composite of Inorganic Quantum Dot Nanocrystals and Organic Cholesteric Liquid Crystals (Advanced Optical Materials 9/2013)




The thermally and electrically tunable lasing emission and amplified spontaneous emission reported by C. R. Lee and co-workers on page 637 is based on a composite of inorganic quantum dots (QDs) and organic cholesteric liquid crystals (CLCs). Considering the merits of CLC microresonators and QD gain media in tunability and stability, respectively, combining the two may create tunable QD coherent light sources or laser devices with desirable advantages.
