Thumbnail image of graphical abstract

Multiple-wavelength distributed-feedback lasers are made from multilayered composites by utilizing the solution-processing ease of cadmium selenide semiconductor nanocrystals and soft lithography. The Figure shows three types of emission obtained from such structures across a wide range of the visible spectrum: fluorescence (dotted lines), amplified spontaneous emission (dashed lines), and feedback-induced lasing (solid lines).
