In article number 1804171, Xiang Yang Liu and co‐workers investigate the self‐collimation effect on fluorescence emission, and the design of a silk fluorescence collimator is applied to a humidity sensor and dye‐sensitized solar cells. This method of complete control of fluorescence emission by introducing mesoscopic ordered structures and its potential applications may significantly broaden the utility...
This work examines the self‐collimation effect of silk materials on fluorescence emission/detection. A macroscopic regulation strategy, coupled with meso‐reconstruction and meso‐functionalization, is adopted to amplify the fluorescence emission of organic fluorescent dyes (i.e., Rhodamine 6G (R6G)) using silk photonic crystal (PC) films. The fluorescence emission can be linearly enhanced or inhibited...
