Abstract :
The spectral response and outgassing characteristics of new, low-voltage phosphors for application in field-emission flat-panel displays, are presented. A variety of tested phosphor materials include combustion synthesized powders and RF diode or magnetron sputtered thin films. These cathodoluminescent materials are tested with e-beam excitation at currents up to 50 μA within the 200-2000V (eg. “low-voltage”) and 3-8 kV (eg. “medium voltage”) ranges. The spectral coordinates are reasonable compared to industrial low-voltage P22 phosphors. Phosphor outgassing is measured with a residual gas analyzer. We find that levels of outgassing stabilize to low values after the first few hours of excitation. The desorption rates measured for powder phosphor layers with different. thicknesses are compared to desorption from thin films
