The surface state of Y 3 (Al,Ga) 5 O 12 :Tb phosphor was determined before and after 27h of prolonged electron beam exposure. The electron irradiation was carried out at a base pressure of 2.3×10 −8 Torr and an oxygen pressure of 1.0×10 −6 Torr. New surface layers were formed after the chemisorbed species were removed as a result of electron stimulated surface...
Tb 3+ -doped Sr 3 (PO 4 ) 2 phosphor was prepared by a sol–gel combustion method. A trigonal structure having Sr and O atoms occupying two different lattice sites were obtained. Scanning Auger nanoprobe was used to analyze the morphology of the particles. Photoluminescence (PL) and cathodoluminescence (CL) properties of Sr 3 (PO 4 ) 2 :Tb powder...
