Lanthanide-doped BiVO 4 semiconductors with efficient photocatalytic activities over a
broad range of the solar light spectrum have been synthesized by the microwave …

Unlike rare earth (RE)(eg, Eu2+) and non-RE (eg, Mn2+) doped tunable solid solutions that
frequently suffer from the visible re-absorption issue, the Bi3+ ion features the remarkable …

It is commonly considered that the upconversion (UC) photocatalytic material is prepared by
at least two steps which the first step is the synthesis of up-conversion fluorescent material …

Upconversion photocatalysts have the potential to absorb the near-infrared (NIR) light in
solar energy and improve the photocatalytic performance. A hierarchical upconversion …

A green emitting Gd (0.95− x) HoxYb0. 05NbO4 phosphor (x= 0.001, 0.005, 0.01, 0.02, 0.03
and 0.035) has been synthesized by the solid-state reaction method. The phosphor samples …

In the last decades, in the field of silicon microphotonics many efforts have been made to
find strategies in order to obtain efficient luminescence from silicon or from Si compatible …

This work reports the high-pressure and high-temperature (HP-HT) synthesis of pure
monoclinic phase of GdNbO 4: Bi 3+ phosphors. X-ray diffraction, field emission scanning …

In this work, Tm3+ and Yb3+ co-doped NaGd (WO4) 2 nanoparticles were synthesized via
surfactant-assisted hydrothermal reactions. The structural analysis indicates that Tm3+ and …

Excitation of Ho3+ and Bi3+ co-doped LaNbTiO6 particles with 453 nm blue light gave an
intense single green glow. All the phosphors were synthesized via a facile sol–gel and …

There are two key factors to design an efficient green upconversion (UC) emission based
optical sensor for temperature. The primary need is to develop a thermally stable and …
