Title: Cheryl M Forster: Innovator in Phosphor Technology
Introduction
Cheryl M Forster is a notable inventor based in Van Etten, NY (US). She has made significant contributions to the field of phosphor technology, holding a total of 5 patents. Her work focuses on improving the performance and efficiency of phosphors used in various applications.
Latest Patents
One of her latest patents is titled "Reduction of lag in yttrium tantalate x-ray phosphors." In this innovation, phosphor lag was reduced to acceptable levels in high lag monoclinic M' yttrium tantalate x-ray phosphors through the addition of minor amounts of europium. Specifically, europium was added to yttrium tantalate phosphors containing terbium and to phosphors formulated with a stoichiometric excess of yttrium. Another significant patent is for the "Synthesis of gamma calcium pyrophosphate." This invention provides a pure gamma calcium pyrophosphate for use in the production of calcium haloapatite fluorescent phosphor host materials. The process involves dissolving dicalcium orthophosphate in a dilute solution of nitric acid in water, spray-drying it to form a calcium phosphate powder, and firing it in air to convert the powder to pure gamma calcium pyrophosphate. This method allows for larger quantities of phosphor to be processed without undergoing dehydration during firing.
