Product News: New Quantaurus-QY for Absolute Quantum Yield Measurements

10 Oct 2011

Hamamatsu Photonics have introduced the new Quantaurus series of compact instruments for measuring the properties of photoluminescent materials such as fluorescent probes, LED phosphors, organic metal complexes, OLED materials and quantum dots.

The new Quantaurus-QY measures quantum yields faster and easier than the traditional relative method. Based on the established technology of their C9920-02G system, the Quantaurus-QY is a compact system for measuring the absolute quantum yield of light emitting materials in thin film, powder, solid, or liquid form. Liquids can be cooled down to -196°C.

The Quantaurus-QY 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. Analysis includes absolute quantum yield measurement, excitation wavelength dependence, photoluminescence spectrum, photoluminescence excitation spectrum and color coordinates.

The Quantaurus-QY comes in two versions featuring different wavelength ranges. The standard model (C11347-11) covers wavelengths from 300 nm to 950 nm and the NIR model (C11347-12) is suitable for measurements from 400 nm to 1100 nm.
