Cathodophosphors
|
|
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)
