Triplet Sensitization Enables Bidirectional Isomerization of Diazocine with 130 nm Redshift in Excitation Wavelengths
نویسندگان
چکیده
Diazocine (bridged azobenzene) can be switched in both directions upon selective excitation of two different coexisting triplet sensitizers. Compared to direct irradiation, switching wavelengths are strongly (≥130 nm) bathochromically shifted.

Standoff detection of biological agents using laser induced fluorescence—a comparison of 294 nm and 355 nm excitation wavelengths
Standoff detection measuring the fluorescence spectra of seven different biological agents excited by 294 nm as well as 355 nm wavelength laser pulses has been undertaken. The biological warfare agent simulants were released in a semi-closed aerosol chamber at 210 m standoff distance and excited by light at either of the two wavelengths using the same instrument. Significant differences in seve...

متن کاملReproducibility of helium-neon laser wavelengths at 633 nm.
Measurements, performed at NBS, NPL, and PTB, on helium-neon lasers stabilized on the Lamb dip, have shown that the wavelengths of these lasers fell within approximately 1 part in 10(7). Beyond this limit, different lasers were found to emit different wavelengths. In addition, the wavelength of a given laser may vary during the life of its discharge tube. Pressure shifts appear to be a major ca...
متن کاملDistributed Humidity Sensing in PMMA Optical Fibers at 500 nm and 650 nm Wavelengths
Distributed measurement of humidity is a sought-after capability for various fields of application, especially in the civil engineering and structural health monitoring sectors. This article presents a method for distributed humidity sensing along polymethyl methacrylate (PMMA) polymer optical fibers (POFs) by analyzing wavelength-dependent Rayleigh backscattering and attenuation characteristic...
