CRT (Cathode Ray Tube) phosphors are excited by a beam of electrons generated by an electron gun within the CRT. Phosphor Technology manufactures a range of phosphor powders designed for use in CRTs.
CRT phosphors are frequently referred to by P numbers as specified by the Electronics Industries Assciation (EIA) of the US. A unified Worldwide Phosphor Type Designation System (WTDS) using one or two letter codes was developed later on. Listed below is the range of PTL phosphors for CRTs with their EIA and WTDS designations and corresponding PTL grade.
