Method for manufacturing photoconductive layers that constitute radiation imaging panels
View Patent ↗Bi 12 MO 20 material particles with a diameter of 0.1 to 2 μm, which are filled in an aerosolization chamber, are shaken/agitated together with carrier gas in a high-pressure gas cylinder which stores the carrier gas, thereby being aerosolized. The aerosolized Bi 12 MO 20 material particles are injected together with the carrier gas onto a substrate from a nozzle in a film-forming chamber, the nozzle including a narrow opening, and the Bi 12 MO 20 material particles are deposited onto the substrate, thereby being formed into a film.
1. A method for manufacturing a photoconductive layer that constitutes a radiation imaging panel which records radiation image information as an electrostatic latent image, wherein material particles of the photoconductive layer are mixed with carrier gas, accelerated and injected by the carrier gas, and deposited on a substrate, thereby being formed into a film;
wherein the photoconductive layer is formed of Bi 12 MO 20 (where M is at least one of Ge, Si and Ti);
wherein a particle diameter distribution of the material particles of the photoconductive layer is set so that particles with a particle diameter of 0.1 to 2 μm occupy 70 wt % or more; and
wherein the temperature of the substrate when the material particles of the photoconductive layer are deposited is 100° C. to 300° C.
