The New Quantaurus Series Offers Quick, Easy Measurements of the Fluorescence Lifetime and Quantum Yield of Photoluminescent Materials

(Nanowerk News) Hamamatsu Photonics has introduced the new Quantaurus series of compact instruments for measuring the properties of photoluminescent materials. The new Quantaurus-Tau measures fluorescence lifetimes as short as 100 picoseconds, while the Quantaurus-QY measures quantum yields faster and more easily than the traditional relative measurement method. The combination of these two instruments enables a comprehensive characterization of photoluminescent materials such as fluorescent probes, LED phosphors, organic metal complexes, OLED materials, and quantum dots. The Quantaurus series can be used to analyze materials in thin film, powder, solid, or liquid form. Liquid samples can be cooled down to -196 degrees Celsius.
The Quantaurus-Tau lets users quickly and easily measure the fluorescence lifetime of photoluminescent materials from sub-nanoseconds to the millisecond range with single-photon-counting sensitivity. The two available models cover a spectral range from 300 nm to 800 nm (C11367-11) and from 380 nm to 1030 nm (C11367-12). Operation is simple, and the dedicated software includes a variety of measurement and analysis functions. Seven LEDs allow sample excitation from 280 nm to 630 nm. Furthermore, Quantaurus-Tau features optional add-ons for performing phosphorescence measurements.
The Quantaurus-QY offers a fast, easy way to measure the quantum yield of photoluminescent materials. It performs absolute measurements and does not require known reference samples, in contrast to the traditional relative method. Operation is simple and intuitive, from selecting excitation wavelengths to making a variety of measurements with various analysis functions. Analyses include photoluminescence quantum yield measurement, excitation wavelength dependence, photoluminescence spectrum, photoluminescence excitation spectrum, and color coordinates. The Quantaurus-QY is available in two models with different wavelength ranges: the standard model (C11347-11) covers wavelengths from 300 nm to 950 nm, and the NIR model (C11347-12) covers the region from 400 nm to 1100 nm.
