Cathodophosphors
Cathodophosphors - application    Provide for observation of signals with a persistence of 10-10 - 10-2 s in any CRT constructions; are used in single-crystal scintillators.
Main types of the produced cathodoluminescent phosphors:
  • Cathodophosphors for color and monochrome display and projection tubes (Table 1)
  • Mid-voltage cathodophosphors for flat-panel field-emission displays (FEDs) (Table2)
Cathodophosphors - persistence time, scintillators, tomography, radars, oscillography, photorecording, television, sec
