Impurity do** is a promising method to impart new properties to various materials. Due to
their unique optical, magnetic, and electrical properties, rare-earth ions have been …

Composites or hybrid materials offer diverse properties not achievable in pure materials.
Here we critically review the interesting and controllable fluorescence and photothermal …

Herein, we demonstrate video-rate color three-dimensional (3D) volumetric displays using
elemental-migration-assisted full-color-tunable upconversion nanoparticles (UCNPs). In the …

Energy-intensive technologies and high-precision research require energy-efficient
techniques and materials. Lens-based optical microscopy technology is useful for low …

Recently high do** of lanthanide ions (till 100%) is realized unprecedentedly in
nanostructured upconversion (UC) phosphors. However, oddly enough, this significant …

The development of blue/green/red tricolor upconversion (UC) phosphors under invisible
light irradiation has attracted significant interest in emerging applications such as anti …

In this study, up-conversion fluoride phosphors NaY1− xy− m− nMxF4: Er3+ y, Ho3+ m,
Yb3+ n (M= Lu3+/Gd3+) were synthesized by a low-temperature combustion method. The …

Ghost imaging captures 2D images with a point detector instead of an array sensor. It could
therefore solve the challenge of building cameras in wave bands where sensors are difficult …

High-power density applications using up-conversion (UC) systems rely mostly on the Yb,
Tm lanthanide couple. Herein, we investigate the extent to which Gd high energy levels can …

Super‐resolution fluorescence microscopy is of great interest in life science studies for
visualizing subcellular structures at the nanometer scale. Among various kinds of super …
