Abstract. With the proliferation of high-intensity neutron sources and involvement of scientists from diverse areas, it is important to provide methods for remote access and display of data. We have developed an integrated spectral analysis workbench (ISAW) that can read, merge or combine, operate on, and visualize large arrays of data. ISAW is written in Java to allow it to run on common user workstations...
Abstract. GdVO4 with activators Eu, Dy, Sm and Bi has been synthesised by a solid-state reaction. GdVO4:Eu3+ (3%) yielded the highest quantum efficiency of 95%. Interesting energy-transfer properties have been revealed in the mixed-activator phosphor (GdVO4:Eu3+, Sm3+) when excited in the 4f shell of Sm3+ at 408nm. Bismuth-activated GdVO4 gives rise to a broad-band emission peaking at 525nm in comparison...
