A series of Sm3+-activated molybdates Li3Ba2(La1−xSmx)3(MoO4)8 with 0<̲x<̲1 (0% to 100% Sm3+) have been prepared by the conventional solid-state synthesis method, and their optical properties were investigated. Reflection, excitation and emission spectra were recorded and put in relation to the various [Xe]4 f 5 → [Xe]4 f 5 transitions of Sm3+. The positions of the charge transfer bands of Sm3+ and Mo6+ were resolved by Gaussian peak fitting. Emission spectra recorded at 100 K revealed the…

New Red-Emitting Phosphor La2Zr3(MoO4)9:Eu3+ and the Influence of Host Absorption on its Luminescence Efficiency

This work investigates the optical properties of Eu3+-activated La2Zr3(MoO4)9. A series of solid solutions with Eu3+ concentrations in the range of 0–100 % were prepared by conventional high

(INVITED) Eu3+ activated molybdates – Structure property relations

Photoluminescence and energy transfer behavior of narrow band red light emitting Li3Ba2Tb3(MoO4)8:Eu3.

It is finally demonstrated that the application of a Eu3+/Tb3+ co-doped ceramic disc is useful for the colour conversion of a blue emitting LED with a higher conversion rate compared to Li3Ba2(La1-xEux)3(MoO4)8.

On the crystal structure and optical spectroscopy of rare earth comprising quaternary tungstates Li3Ba2RE3(WO4)8 (RE = La-Nd, Sm-Ho).

The quaternary tungstates Li3Ba2RE3(WO4)8 (RE = La-Nd, Sm-Ho) were obtained by a ceramic synthesis route and were characterized by powder and single crystal X-ray diffraction, and showed blue CT luminescence caused by tungstate units, while the other samples show typical and multiple lines due to well known [Xe]4fn → [Xes4fn transitions.

Single Crystals of KRE(MoO4)2, (RE‐ Ce, Pr) Obtained from Fluorides: Scheelite‐Related Structure and Luminescence

Single crystals of double molybdates KRE(MoO4)2 (RE = Ce and Pr) have been prepared from high‐temperature melts by a facile and effective fluoride‐assisted method, and investigated by XRD, FTIR and

Luminescence and Luminescence Quenching of K2Bi(PO4)(MoO4):Eu3+ Phosphors with Efficiencies Close to Unity.

Temperature dependent luminescence measurements showed that phosphor performance increases with increasing Eu3+ concentration, and these phosphors possess a very unique emission spectra; thus, they could also be applied in luminescent security pigments.
