ZnGa 2 O 4 nanospheres with high uniformity are synthesized by a facile hydrothermal method with the assistance of organic additive trisodium citrate (Cit3‐). On page 6581 M. Shang, J. Lin, and team show how, under UV light and low‐voltage electron beam excitation, ZnGa 2 O 4 , ZnGa 2 O 4 : Mn 2+ , and ZnGa 2 O 4 : Eu 3+ nanospheres emit bright blue, green, and red luminescence, respectively. A wide range of tunable color including white emission is obtained through changing the relative amount of the Mn 2+ and Eu 3+ ‐doped samples, indicating this material can be used in future lighting and display systems.
