A series of novel Eu3+-activated La2MoO6-La2WO6red-emitting phosphors have been successfully prepared by a citrate-assisted sol-gel process. Both photoluminescence excitation and emission spectra suggest that the resultant products have the strong ultrabroad absorption band ranging from 220 to 450 ...
Then, 0.95 mmol of Ca(NO3)2·4H2O (99.9%, Wako), 0.05 mmol of Eu(NO3)3·6H2O (99.95%, Wako), and 1.00 mmol of Al(NO3)3·9H2O (99.9%, Wako) were further dissolved in the above solution, giving a cation molar ratio of Ca2+:Eu3+:Mo6+:Al3+ = 0.95:0.05:1:1. Then, 1.2...
