Eu3+-Y3+ co-doped (Sr0.88-x-1.5yCaxEuyY0.08)(Mo0.2 W0.8)O4(x=0.20, 0.30, 0.40, 0.50, 0.60, 0.70. y=0.02, 0.04, 0.06, 0.08, 0.10, 0.12, 0.16, 0.20) were prepared by sol-gel method, and their crystal structures and luminescent properties were investigated. Through XRD, photoluminescence spectra analyses and powder size measurements, changing Ca2+ concentration, Eu3+ concentration and charge compensators components were performed for optimization its emission property. It was found that, with 2 mol% 0.6Li2CO3-0.4K2CO3 charge compensation, (Sr0.26Ca0.5Eu0.08Y0.08)(Mo0.2 W0.8)O4 possesses better emission property than the commercial phosphor Y2O2S:Eu3+..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
