A judicious choice of the lanthanide cation and its content in the Na 3 (Y 1– a M a )Si 3 O 9 (M=Tm 3+ , Tb 3+ ; a = 0–1) system allows the optical properties to be tuned over a very wide range. The materials have the same framework structure and encompass thulium‐based blue‐ and infrared‐emitters and terbium‐based X‐ray phosphors (see spectra in Figure). The emission can be controlled in some infrared regions by varying the Y 3+ /Tm 3+ molar ratio.
