| Zusammenfassung: | Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Widely tunable laser action by low threshold optical excitation can be realized by a colloidal crystal gel (CC-G) film permanently stabilized by a non-volatile ionic liquid. The CC-G film consists of a non-close-packed structure of microparticles immobilized in a polymer gel. Optical excitation with green light gives rise to a single and very narrow laser emission with red color. The single laser emission peak can be tuned in a wide wavelength range by applying mechanical stress |
