Due to events of the past two decades, there has been new and increased usage of
radiation-detection technologies for applications in homeland security, nonproliferation, and …

It is well known that the optical response of a medium depends on the local field acting on
an individual emitter rather than on the macroscopic average field in the medium. The local …

Nanocrystals (NCs) doped with luminescent ions form an emerging class of materials. In
contrast to excitonic transitions in semiconductor NCs, the optical transitions are localized …

Strong visible emission under UV (320nm) and IR (967nm) excitation on ZrO2: Sm3+ and
ZrO2: Er3+ nanophosphors were obtained and the concentration effect on the luminescence …

Silica glasses containing both ZnS quantum dots (QDs) and luminescent lanthanide ions are
attractive candidates to develop new lighting displays, sensor devices or laser emitters. This …

Lanthanide‐based upconverting nanoparticles (UCNPs) are trustworthy workhorses in
luminescent nanothermometry. The use of UCNPs‐based nanothermometers has enabled …

Nanocrystalline ZrO2: Dy3+ were prepared by sol–gel and the structural and
photoluminescence properties characterized. The crystallite size ranges from 20 to 50nm …

The structure, luminescence spectroscopy, and lifetime decay dynamics of Eu2O3
nanoparticles formed in MCM-41 have been investigated. Both X-ray diffraction and high …

Cubic Gd2O3: Eu3+ (0.30, 1.01, 2.78, and 4.60 mol%) nanorods with an average diameter
of ca. 14 nm were synthesized at ambient pressure and mild temperature (70° C), using a …

Optical fiber‐based lasers and amplifiers are ubiquitous tools across many practical
applications including communications, metrology, sensing, manufacturing, machining, and …
