A review on fluorescent inorganic nanoparticles for optical sensing applications

Abstract

Fluorescent inorganic nanoparticles are immerging novel materials that can be adopted for a large number of optical bioassays and chemical sensing probes.

The Bright X‐Ray Stimulated Luminescence of HfO2 Nanocrystals Activated by Ti Ions

“…In recent years, modern synthesis routes have led to the fabrication of new nanoscale materials with outstanding optical properties arising from their improved crystal phase and composition, narrow size distribution, and uniform shape . Luminescent NPs—metals, semiconductors, or insulators—have come to the forefront in modern solid state physics, lighting, next generation electronics, and sensing, in the environmental and life science, as well as in medical and biological fields . In particular, extensive theoretical and spectroscopic studies of the optical response of inorganic luminescent NPs have been proving the suitability of these systems in the field of phosphors and scintillators for lighting and radiation detection applications .…”

Effect of Incubation Time, CuSO4 and Glucose Concentrations on Biosynthesis of Copper Oxide (CuO) Nanoparticles with Rectangular Shape and Antibacterial Activity: Taguchi Method Approach

“…Compared with bulk materials, NPs have attracted more attention due to their unique specific properties such as higher surface area to volume (SA:V) ratio [3,4], which results in various applications in biology and medicine [5,6], optical sensors [7], cosmetics [8], food industry and household products [9,10]. These applications are resulted from SA:V ratio of NPs that lead to NPs with high surface energy [11].…”

Pd nanocube decoration onto flexible nanofibrous mats of core–shell polymer–ZnO nanofibers for visible light photocatalysis

“…5a-c calcination leads to a reduced visible emission intensity for ZnO but oxygen vacancies still play a huge role in the ZnO emission, embarking with the delocalized charge carrier involvement leading a large dipole moment variation causing a possible transfer to the attached fluorophore actors. 49,50 Accordingly, one can expect the energy transfer from the defect centers as donors to the acceptor structures, but the results are completely different, causing a different interpretation for the conducted experiments. Förster energy transfer theory with dipole moment calculations was utilized to explain the mechanism of the energy transfer from defect states close to the surface, but the donoracceptor distance was small for the covalently bonded fluorophores.…”
