Abstract
La presente invenzione si riferisce a nuovi fosfori per l'uso in pannelli, apparati e metodi per registrare riprodurre l'immagine di una radiazione ad alta energia, che includono le fasi di stimolare un fosforo esposto a guisa di immagine alla radiazione e rilevare la luce fluorescente emessa da detto fosforo sotto stimolazione, detto fosforo essendo un tantalato di metallo alcalino attivato con terbio emettente nel verde, drogato con almeno un elemento scelto nel gruppo comprendente Mg, Ca, Sr, Ba, Al, Ga, Ge, Pb, Bi, elementi di transizione e lantanidi.
