WebThe two mostly used phosphor screens for image intensifiers are P43 and P46. The P43 phosphor screen has a higher efficiency and higher spatial resolution due to smaller grain size. However, it has a long decay time. For fast applications e.g. double frame mode with an interframing time of 500ns the faster decaying P46 phosphor screen is ... WebPhosphor materials used in PDP must have high QE (quantum efficiency), low reflectivity in VUV, and must be stable and highly reflective for visible light. State of the art phosphors …
