The modulation of luminescence is essential because unwanted spontaneous‐emission
modes have a negative effect on the performance of luminescence‐based photonic devices …

Metal nanoparticle plasmons or the photonic crystal effect are being widely used to modify
luminescence properties of materials. However, coupling of surface plasmons with photonic …

Triclinic Gd1-x Eu x BO3 nanophosphors have been prepared by a hydrothermal method
without using additional coreagents and prior precipitation of precursor (in situ). The …

In this article, we fabricated Y2Ti2O7: Yb, Er, Tm upconversion inverse opal photonic
crystals with energy transfer between Er3+ and Tm3+, and investigated the influence of the …

The narrow band gap semiconductor LaFeO 3 with ABO 3 perovskite structure has been
deeply studied in the field of photocatalysis due to its good thermal stability, chemical …

Down-and upconversion luminescence phenomena from YBO 3 materials doped by Yb 3+
and Tb 3+ ions were observed and investigated. Materials described in the article were …

Comprehensive investigations of near infrared (NIR) downshift and visible upconversion
luminescence (UCL) mechanisms were carried out for Yb3+ single-doped and Er3+, Yb3+ …

YBO3: Ce3+ blue-emitting phosphors were prepared from boric acid and nitrates of yttrium
and cerium (III) by hydrothermal method. An excess amount of boric acid, prolonged aging …

The enhancement of Er3+-based up-conversion for photovoltaics in multilayer porous silicon
photonic structures is considered theoretically and experimentally. Transfer matrix …

We investigated the upconversion (UC) properties of YBO 3 co-doped with Er 3+ and Yb 3+
ions. The YBO 3 samples were synthesized by the solid state reaction method. The Er 3+ …
