Increased interest in research and applications of nanoparticles requires rapid qualitative and quantitative analysis of nanoparticle samples. The development of the NanoLog spectrofluorometer and associated Nanosizer software takes advantage of nanoparticles’ fluorescence in the near-IR, and allows researchers to rapidly and accurately assess the composition and properties of samples of single-wall carbon nanotubes and quantum dots.
HORIBA Jobin Yvon’s NanoLog spectrofluorometer, specially optimized for recording near-IR fluorescence from nanoparticles, includes a double-grating excitation monochromator, imaging emission spectrograph with a selectable-grating turret, and a variety of detectors. It has optimal excitation optics1 for single-wall carbon nanotube (SWNT) research or any solid sample in right-angle or front-face mirror configurations. The NanoLog can be customized to provide steady-state and lifetime information about quant um dots as well, for quant um- dot photoluminescence is becoming an important tool in the fields of materials science, biology, medicine, and energy.
