Synthesis and photoluminescence properties of MgAl 2 O 4 :Eu 3+ phosphors
Source abstract
Abstract
Abstract Nano-sized Mg 1– x Al 2 O 4 : x Eu 3+ (0.02≤ x ≤0.1) red phosphors are prepared by the solution combustion method. Mg 1− x Al 2 O 4 : x Eu 3+ phosphors can be effectively excited by near-UV (396 nm) and exhibit a satisfactory red emission (615 nm). The emission intensity of the electronic dipole 5 D 0 → 7 F 2 transition at 615 nm is much stronger than that of the magnetic 5 D 0 → 7 F 1 transition at 590 nm, which is indicative of a high-purity red color emission. It is believed that the photoluminescence properties of Mg 1− x Al 2 O 4 : x Eu 3+ phosphors can be improved by controlling the annealing temperature and Eu 3+ concentration. The Mg 1− x Al 2 O 4 : x Eu 3+ shows great potential as a red-emitting phosphor for light-emitting diode applications.
