✦ Synopsis

The crystal structure of strontium dialuminodiborate SrAl 2 B 2 O 7 has been established by single-crystal X-ray di4raction methods. The compound crystallizes in the trigonal system (space group R3 c, Z ‫؍‬ 6) with cell parameters a ‫؍‬ 4.893(1) A > and c ‫؍‬ 47.78(1) A > . Aluminium and boron atoms are, respectively, in tetrahedral and triangular oxygen coordination. The assembly of Al 2 O 7 units and BO 3 triangles forms double layers between which Sr 2Ψ‰ ions are located. The Eu 2Ψ‰ -doped crystalline powder exhibits a luminescence band with maximum at 415 nm. Luminescence characteristics are compared to those of other strontium borates.

## Abstract A novel blue green‐emitting phosphor Ba~2~ZnSi~2~O~7~ : Eu^2+^ was prepared by combustion synthesis method and an efficient bluish green emission under from ultraviolet to visible light was observed. The emission spectrum shows a single intensive band centered at 503 nm, which correspon
