✦ Synopsis

The nanosized yttrium scandium gallium garnet Y 3 Sc 2.5 Ga 2.5 O 12 (YSGG) was synthesized by an aqueous sol-gel route.

The discovery of advanced oxide phosphors with multiple superior qualities for display applications remains a difficult problem. Specific luminescence properties are highly sensitive to the host material, changes in dopant composition and host stoichiometry. The matrix of phosphors should possess good chemical, mechanical, thermal and optical characteristics. [1][2][3][4][5] Transition and rare-earth metal ions have demonstrated a lasing action in various host crystals. For example, rare-earth aluminium garnets have attracted considerable attention as host crystals for near-infrared solid-state lasers and optoelectronics devices. [6][7][8][9] Among the compounds that can incorporate transition metals or lanthanides, several scandium-and gallium-based materials were also elaborated. [10][11][12][13][14][15] Recently, we reported on the synthesis of substituted yttrium aluminium garnets: Y
