Vacuum Ultraviolet Luminescence Characterization System
To develop vacuum ultraviolet excitable phosphors the Institute of Low Temperature and Structure, Polish Academy of Science contracted McPherson to build a characterization system for the 120nm to 1800nm range. The benign discharge of a noble gas will replace Mercury excitation, for phosphor emission under environmentally acceptable conditions.
- (1888PressRelease) May 11, 2011 - The research group, led by Prof. Przemysław Dereń, plan to use the McPherson system to measure and characterize luminescence properties of phosphors and crystals. The research is intended to help create more efficient methods of commercial lighting. There is still work to be done in order to realize a viable, efficient vacuum ultraviolet (VUV) excited phosphor. Such a phosphor will solve two important problems; ecological and efficiency. Today's compact fluorescent lamps (CFL) often still use Mercury, harmful to humans and nature. The new VUV phosphors are instead excited by environmentally benign discharge in noble gasses. The VUV phosphors will be twice as energy efficient as today's CFL's.
The new spectrometer system from McPherson will be used to study quantum cutting phenomenon and eventually to obtain a new class of lighting. The McPherson instrument enables research efforts by allowing tunable, monochromatic vacuum ultraviolet wavelength sample excitation and subsequent emission measurements from the vacuum ultraviolet to the near infrared. At a significantly reduced price from working on synchrotron storage rings.
