A phosphor analyzer that delivers vacuum-UV excitation wavelengths at 146 and 173 nm has been introduced by McPherson Inc. The device features plasma-display-panel technology, a spectrometer for phosphor emission analysis and a CCD for determining the emission wavelength. The phosphor samples can be exchanged while maintaining the vacuum required for high-energy excitation, and they can be analyzed in more detail in single-channel mode. The system also can be equipped with tunable monochromatic light sources for excitation from 115 to 350 nm and with high-gain photomultipliers for scanning spectra.
