Problems solved by technology

However, the excitation wavelength peak of this kind of optical storage luminescent material must be near the wavelength emitted by these lasers, otherwise it will cause blurred images, poor gray scale, and even unreadable images
In addition, the relatively expensive and bulky defects of this type of laser are accompanied by people's higher and higher requirements for ease of use. People hope to replace the yttrium aluminum garnet used in the short-wave band with the existing cheap and compact semiconductor lasers. Neodymium-doped (Nd:YAG) lasers, argon-ion lasers, or helium-neon lasers

Abstract

The invention belongs to luminous materials for optical storage, in particular relating to a luminous material for optical storage of TaVIn1-xMxSBrF1-yIy: Rez, Au0.1, which is employed to detect diagnostic images of X-ray of medical treatment and is coactivated by rare earth and cadmium ion which are coated on the surface of polymer with industrial nondestructive inspection. The invention also provides a process for preparing the luminous material for optical storage. The novel luminous material for optical storage of the invention is matched with an adjustable broad band of which the wavelength is between 650 nanometers and 1000 nanometers, and the adjustable broad band suits all semiconductor lasers in the wave band, wherein the semiconductor lasers are taken as driving light sources matched with the adjustable broad band, thereby greatly improving utilization convenience of a x-ray image plate which is produced by employing the sample to coat and increasing elastic range of choosing the matching driving light sources. In particular, the luminous property of the invention is further promoted by coating the surface via the polymer.
