    Abstract

    The methodology of parallel synthesis based on the polymerizable complex method is described in this work. A model system such as AxGa yOz (A = Mg, Ca, Sr, Ba) was used to test the proposed approach and to find potential hosts for Tm3+ activated blue light emission phosphor materials. It was found that Ca-containing compounds as hosts are superior to the other alkaline-earth containing materials in this system. The composition Ca5Ga6O14:Tm3+ demonstrated excellent color purity with CIE coordinates x= 0.16, y = 0.12 and it had emission intensity corresponding to the 68% peak intensity of commercial BAM ((Ba, Eu)MgAl10O17)-one of the strongest blue emission phosphor.
