Luminescent properties of Eu3+-activated molybdate-based novel red-emitting phosphors for LEDs

Effect of cation vacancies on the crystal structure and luminescent properties of Ca 0.85−1.5x Gd x Eu 0.1 □ 0.05+0.5x WO 4 (0 ≤ x ≤ 0.567) scheelite-based red phosphors

“…The structure can accommodate a variety of chemical species in both A-and B-cation sublattices, which gives rise to a plethora of different compounds with a general composition (A',A'')a[(B',B'')O4]b, where A', A'' can be alkali, alkali-earth or rare-earth cations and B', B'' are typically W 6+ , Mo 6+ or other cations with tetrahedral coordination. Scheelites containing rare-earth cations demonstrate luminescent properties and can be used in pc-WLEDs (phosphor-converted white-light-emitting-diode) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

Microwave-assisted solvothermal synthesis and characterization of SnO2:Eu3+ phosphors

“…Rare-earth luminescent materials have been widely used for electrical and optical applications including glass scintillators, rareearth coordination polymers, lighting equipment and phosphors for LEDs [1][2][3][4]. Trivalent europium ion (Eu 3+ ) has attracted much attention due to its high luminescent intensity and hypersensitive 5 D 0 → 7 F 2 transition.…”

Phase diagrams for the M2MoO4–Ln2(MoO4)3–Hf(MoO4)2 systems, where M = Li–Cs, Tl and Ln = La–Lu

“…These phosphors should possess high stability, compactness, high luminescence efficiency when excited by near UV, long lifetime and low cost. Luminescent materials containing rare-earth elements are also within the scope of such studies [1][2][3]. In this paper, we present results on the study of phase equilibria in ternary molybdate systems containing single-, three-and tetravalent elements, as well as data on the crystal structure of complex molybdate structural types.…”
