Luminescence of Eu-doped langanite nanopowders synthesized by a citrate sol–gel method

Luminescent properties of UV excitable blue emitting phosphors MSr4(BO3)3:Ce3+ (M = Li and Na)

“…For the phosphors used in near-UV white LEDs, the basically requirements are strong absorption in the near-UV range and high conversion efficiency. Moreover, high chemical and physical stabilities are also important for improving the lifetimes of w-LEDs [6].…”
