A novel multiple heterostructure photonic crystal (MHPC) structure with stopbands overlapping and broadening was demonstrated by Shengyang Tao and co‐workers (see article number 1701344). The MHPC with a super‐wide stopband can simultaneously overlap the excitation and emission wavelength of most fluorescent media and achieve universal fluorescence enhancement, indicating its potential to serve as a fluorescence enhancement sensing platform for the accurate detection of Cr(VI) down to 0.2 ppb.

通过光子晶体结构增强荧光：基于具有多个超阻带和高灵敏度Cr（VI）检测性能的多重异质结构光子晶体的通用荧光增强基底（先进光学材料11/2018）

陶胜阳及其同事证明了一种新型的具有阻带重叠和扩宽的多重异质结构光子晶体（MHPC）结构（参见文章编号1701344）。具有超宽阻带的MHPC可同时重叠大多数荧光介质的激发和发射波长并实现通用荧光增强，表明其潜力可作为荧光增强传感平台，用于精确检测低至0.2 ppb的Cr（VI） 。
