Abstract
The present invention relates, in general terms, to X-ray detecting films and uses thereof. The present invention also relates to methods of fabricating the X-ray detecting films. In particular, the X-ray detecting film comprises persistent luminescent nanoparticles dispersed within a flexible polymer matrix, wherein the persistent luminescent nanoparticles are dispersed in the flexible polymer matrix at a concentration of about 0.1% to about 100%.
