Synthesis and photoluminescence properties of EuVO4 red phosphors

Effects of organic additives on morphology and luminescent properties of Eu3+-doped calcium molybdate red phosphors

“…The emission intensity of 5 D 0 → 7 F 2 transition is much stronger than that of 5 D 0 → 7 F 1 transition, which is in good agreement with the Judd-Ofelt theory: transitions to even J-numbers show much stronger emission intensities compared to those of corresponding neighboring odd J-numbers [35,36]. The value of ( 5 D 0 → 7 F 2 )/ ( 5 D 0 → 7 F 1 ) depends on the local symmetry of Eu 3+ ions and stands for the deviate degree of Eu 3+ from the centrosymmetry [35]. The values of ( 5 D 0 → 7 F 2 )/( 5 D 0 → 7 F 1 ) for CaMoO 4 :Eu 3+ samples with CTAB, DTAC, SDBS, SDS, PVP, PEG20000 are 8.…”

Equation of state and electronic properties of EuVO4: A high-pressure experimental and computational study

“…The structural models were based on the zircon and scheelite structures. The following parameters were refined: the scale factor (1), background parameters (5), lattice parameters (2), M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 5 atomic position parameters (2 or 3), overall atomic displacement parameter (1), peak-width (3) and shape (2) parameters.…”

“…Zircon-type EuVO 4 has interesting luminescence properties [1,2]. It has been concluded that zircon-type EuVO 4 is a valuable red phosphor [3], because it exhibits a strong red emission under both near UV and visible-light excitation. It has also been considered for application in white LEDs [4]; its fluorescence can be used in biology and medicine for monitoring the cells [5].…”

Synthesis and luminescence characterization of Y2BaZnO5:RE (RE = Eu3+, Tb3+, Pr3+ and Sm3+) phosphors

“…According to Judd–Ofelt theory, transitions to even J‐numbers show stronger emission intensities than those of the neighboring odd J‐numbers . The integrated areas of the emission intensities caused by the 5 D 0 → 7 F 1 and 5 D 0 → 7 F 2 transitions were calculated.…”
