南京大学谭海仁团队开发了阴离子工程添加剂策略，来控制宽带隙钙钛矿薄膜的结晶过程。最终，谭老师研究团队不仅提高了钙钛矿薄膜质量，同时也可以让其更好的覆盖在晶硅电池表面，实现了高质量保形沉积。这为更好的发挥钙钛矿/硅叠层电池的潜力提供了契机。相关成果以 “Efficient Perovskite/Silicon Tandem Solar Cells on Industrially Compatible Textured Silicon”发表在Advanced Materials。

Photoluminescence between SWNTs is explained by invoking transfer of excitons via FRET between SWNTs within bundles. The HORIBA Jobin Yvon NanoLog® modular near-IR spectrofluorometer proved indispensable in analyzing such single-wall carbon nanotube samples.

Corrected emission spectra of carbon nanoparticles can provide excitation–emission matrices (EEMs) for a range of excitation wavelengths. Acquisitions take only minutes (λexc = 500–800 nm at 1-nm intervals, λem = 830–1350 nm at ~1 nm per pixel). EEMs are compiled by HORIBA Jobin Yvon’s Nanosizer® software. A double-convolution algorithm (U.S. pat. pending) in the software simultaneously computes excitation and emission wavelength coordinate lineshapes for each species within minutes; contributions from all spectral bands in a region of interest are found.

Near-IR spectra—including matrix scans—from single-wall carbon nanotubes are easily recorded and analyzed using the NanoLog® spectrofluorometer with our Nanosizer™ software. The NanoLog® is useful in a wide array of research related to nanostructures, quantum dots, biomedical research, and materials science for the future.

借助于成熟的FluoroLog技术，Nanolog采用模块化设计，即可实现稳态测量，也可实现瞬态测量（TCSPC技术），系统搭配成像光谱仪，可实现红外三维荧光快速测量。配合吸收附件，可校正“内滤效应”。专为单壁碳纳米管（SWNTs）设计的NanoSizer软件，可计算荧光共振能量传递(FRET)和碳管内径分布。

大部分单壁碳纳米管(SWNTs)的研究聚焦于单管，而对于多管束的研究甚少。根据新的研究结果表明，可以通过检测SWNTs激子研究单管和多管束的电子性质。因此利用HORIBA Scientific（Jobin Yvon光谱技术）设计生产的Nanolog模块式近红外荧光光谱仪，研究SWNTs管束间FRET的光致发光光谱，从而获得SWNT管束的电子性质。

The NanoLog® is an indispensable tool for studying fluorescence lifetimes of samples whose luminescence is primarily in the near-IR, such as quantum dots. Other uses for the NanoLog® include solid-state research, biosensing, and cancer studies. The NanoLog® also available with TCSPC multichannel-scaling options of 500 ns/channel and 2 ns/channel, as well as a broadband 5509 photomultiplier tube, sensitive from 300–1700 nm, with a timetransit spread of 1.5 ns.
