Graphical Abstract
Single crystals and powder samples of NaLnGeO4(Ln= Sm, Eu, Gd, Tb) were prepared via a sodium hydroxide melt and conventional solid-state methods. The three-dimensional crystal structure was determined by single crystal X-ray diffraction. Magnetic susceptibility data were collected and the room temperature photoluminescence was investigated.
