Abstract
The emission colors of transparent suspensions of SrMoO4 :Eu3+,Tb3+ nanophosphors in hexane could be finely tuned for use in multicolor transparent displays. The emission color in the green–red spectral region was tuned by changing the concentrations of the Eu3+ and Tb3+ activator ions. SrMoO4 :Eu3+,Tb3+ nanophosphors with diameters of 5 nm were synthesized via solvothermal reactions in a hexane–water bilayer system consisting of Sr‐oleate, Eu‐oleate, and Tb‐oleate complexes in hexane and an aqueous (NH4 )6 Mo7O24 solution. A simple phase‐transfer method was used to prepare the Sr‐oleate, Eu‐oleate, and Tb‐oleate complexes in hexane from aqueous Sr(NO3 )2, Eu(NO3 )3, and Tb(NO3 )3 solutions with the assistance of sodium oleate, oleic acid, and oleylamine.
