Dibenzoyl-l-cystine as organic directing agent for assembly of visible-light-sensitized luminescent AgGd(MoO4)2:Eu3+ nanowires

Solid phosphors with uniform morphology can be potentially used in optoelectronic and field-effect transistor applications. In this report, AgxGd1−x(MoO4)2:Eu3+ composites with regular 1-D nanowires assisted by pre-coordination of organic structure (N,N″-dibenzoyl-l-cystine) were designed. The as-derived materials could exhibit striking red emissions by multiple excitations especially the longer wavelength at 466 nm. Furthermore, Ag/Gd ratio was optimized as 1/4. It would be promising to extend the use of ligand-directing agents for the synthesis of a range of novel phosphors.
