Preparation and photoluminescence properties of praseodymium-activated LaInO3 used as a red-emitting phosphor
2017
Rare-earth Pr3+ doped LaInO3 red-emitting phosphors were synthesized by a conventional high temperature solid-state
method at mosphere. X-ray diffraction (XRD) and molecular fluorescence spectrometer were made use of to characterize the
crystal structure and photoluminescence properties of the phosphors, respectively. The XRD analysis indicates that the
phosphor presents pury crystalline phase. The excitation spectrum illustrates that the phosphor has severval sharp peaks at
at 444nm (3H4→3P2), 468nm (3H4→1
I6), 477nm (3H4→3P1) and 488nm (
3H4→3P0). At the same time, the emission spectrum
shows that there are two strong emission peaks in the as-prepared phosphor located at 611nm (1D2…
