BRIDGEWATER, N.J., Nov. 22, 2010 — Hamamatsu Corp.’s Quantaurus-QY is a compact, integrated solution for quickly and easily measuring the quantum yield and other properties of photoluminescent materials. It measures fluorescent probes, dye-sensitized photovoltaic materials, LED phosphor, organic metal complexes, organic LED materials and quantum dots. The device performs absolute (not relative) measurements quickly, without the need to prepare reference samples. It can be used to analyze thin films, powders, solids and solutions. Contained within the compact package is everything needed to capture instantaneous measurements with high sensitivity. This includes an excitation light source (xenon lamp and monochromator), an integrating sphere with optional nitrogen gas flow and a high-sensitivity CCD sensor. The system also includes dedicated software for selecting excitation wavelengths and making a variety of measurements and analyses, including photoluminescence quantum yield measurement, excitation wavelength dependence, photoluminescence spectrum and photoluminescence excitation spectrum. Two models are available. The standard C11347-01 covers wavelengths from 300 to 950 nm, and the near-infrared C11347-02 covers 400- to 1100-nm wavelengths.
