The methodology of parallel synthesis based on the polymerizable complex method is described in this work. A model system such as A_xGa_yO_z (A=Mg, Ca, Sr, Ba) was used to test the proposed approach and to find potential hosts for Tm^<3+> 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 Ca_5Ga_6O<14> : Tm^<3+> 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) MgAl_<10>O_<17>) -one of the strongest blue emission phosphor.
