The resulting materials were characterized by x-ray diffraction, Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Photoluminescence. Those spectra reveal that by adding SiO2 to YAG:Ce precursor, the lattice constant decreases while vacancies are generate due to the co-dopant ions (Si4+) replaces in the place of Al3+ sites of YAG:Ce system. YAG:Ce phosphors with Y3+ dodecahedral site replaced by Ce3+ and diffused effectively as an activator, as a result the photoluminescence intensity increased about ~20-30%.

Network economy could reduce costs of exchange and achieve economies of scope and economies of integration. The advancements of network economy urge it to be the mainstream over obstacles. It shifts situations between supplier and demander, changes the characters of demanding and factors of purchasing. Those engender new type of demand. Estate agencies, which integrate on-line and off-line services, will achieve dominancy in the market. In general, estate agencies have to shift from the necessary intermedia to assistant roles. Network economy supplies a gap of information deficiency in estate market and levels down the amplitude of estate economy cycle. Informatization of industry management enhances market efficiency, at the same time decreases systemic risks.
