Abstract
A method is provided for improving the x-ray screen brightness of gadolinium oxysulfide x-ray phosphors. The method applies annealing and acid washing steps in a specific order following deagglomeration of the phosphor in order to ameliorate the loss of brightness caused by the deagglomeration.
