Most of the blue phosphors are based on Eu2+ or Ce3+ doped compounds. The luminescent centers of Eu2+ or Ce3+ generally require reducing environment during synthesis. Also, Eu2+ and Ce3+ are prone to oxidation, causing instability of the phosphors for long-term use. Herein, we report Bi3+ and Dy3+ c...
