Abstract

PURPOSE:To manufacture a radiation exciting fluorescent screen, which has no distortions in its output images and has a high sensitivity and high resolving power, by providing a CsI phosphor deposition layer with large thickness on a phosphor grain deposition layer formed on a flat base plate, and being followed by providing a CsI phosphor deposition layer with high density over the flat base plate. CONSTITUTION:After the temperature of a base plate 8 with a flat surface is made to be 20-150 deg.C, a phosphor is applied for vapor deposition in an atmosphere with a vacuum degree of 1X10<-3>-1X10<-2>Torr so as to form a first vapor deposition layer 21 with a mean crystal-grain size of below 15mu. Next, in an atmosphere with a vacuum degree of 1X10<-4>-1X10<-2>Torr, a second vapor deposition layer 22 consisting of columnar crystal lumps of an alkaline halide phosphor, such as a CsI phosphor, each of which has a length over 10 times that of the layer 21 and is grown on each crystal grain or over the protruding surfaces of plural grains of the layer 21, is formed. After that, a third vapor deposition layer 23, which consists of a dense CsI phosphor and has a thickness of below 30mu, is formed over the layer 22 in an atmosphere with a high vacuum degree of below 1X10<-5>Torr. Thus, a radiation exciting fluorescent screen is manufactured.
