<I>RE</I><SUB>2</SUB>O<SUB>2</SUB>CN<SUB>2</SUB> (<I>RE</I> = La, Eu, and Gd) and Eu-doped <I>RE</I><SUB>2</SUB>O<SUB>2</SUB>CN<SUB>2</SUB> (<I>RE</I> = La and Gd) phosphors were prepared by nitridation of oxide precursors through rare earth citrate gel. This preparation method increased the doping limit to 20 atom % in La<SUB>2</SUB>O<SUB>2</SUB>CN<SUB>2</SUB>. The value was considerably wider than 7 atom % of solid-state synthesis through rare earth oxide. Eu-doped Gd<SUB>2</SUB>O<SUB>2</SUB>CN<SUB>2</SUB> was firstly synthesized by this method. The shape of luminescence spectra and luminescence intensity were different between these oxycyanamides reflecting the difference in their crystal structure and crystallinity.
