  author={Chao Mi and Jiajia Zhou and Fan Wang and Dayong Jin},
Nanoparticles with anti-Stokes emissions have enabled many sensing applications, but their efficiencies are considerably low. The key to enable the process of anti-Stokes emissions is to create phonons that assist the excited photons to be pumped from a lower energy state onto a higher one. Increasing the temperature will generate more phonons, but it unavoidably quenches the luminescence. Here by quantifying the number of phonons being generated from the host crystal and those at the surface…

Upconverting NIR-to-NIR LuVO4:Nd3+/Yb3+ Nanophosphors for High-Sensitivity Optical Thermometry.

A phonon-assisted upconversion in LuVO4:Nd3+/Yb3+ nanophosphors was successfully applied for temperature measurements within the 323-873 K range via the luminescence intensity ratio technique, showing the way to enhance the thermometric characteristics of contactless optical sensors.

Abnormal thermally enhanced upconversion luminescence of lanthanide-doped phosphors: proposed mechanisms and potential applications

Luminescent materials usually suffer from luminescence thermal quenching because of the aggravation of various nonradiation relaxations with elevated temperatures. However, recent discovery on the

Lanthanide-based ratiometric luminescence nanothermometry

Luminescent nanothermometry can precisely and remotely measure the internal temperature of objects at nanoscale precision, which, therefore, has been placed at the forefront of scientific attention.



Activation of the surface dark-layer to enhance upconversion in a thermal field

Thermal quenching, in which light emission experiences a loss with increasing temperature, broadly limits luminescent efficiency at higher temperature in optical materials, such as lighting

Heterogeneously Nd3+ doped single nanoparticles for NIR-induced heat conversion, luminescence, and thermometry.

It is noticed that while temperature sensitivity and luminescence intensity are optically stable, increased excitation intensity to generate heat above room temperature may saturate the sensing capacity of temperature feedback, so a dual beam photoexcitation scheme is proposed as a solution for possible light-induced hyperthermia treatment.

Mechanistic Investigations on the Dramatic Thermally Induced Luminescence Enhancement in Upconversion Nanocrystals

Luminescent bulk materials generally suffer from thermal quenching, while upconversion nanocrystals (UCNCs) have recently been found to show increase of dramatic emission at elevated temperatures. A

These engineered nanocrystals offer saturation intensity two orders of magnitude lower than those of fluorescent probes currently employed in stimulated emission depletion microscopy, suggesting a new way of alleviating the square-root law that typically limits the resolution that can be practically achieved by such techniques.

Before the 1960s, all anti-Stokes emissions, which were known to exist, involved emission energies in excess of excitation energies by only a few kT. They were linked to thermal population of energy

This systematic study of upconversion nanoparticles reveals power-dependent luminescence enhancement from the inert shell, which explains the discrepancy in enhancement factors reported by ensemble and previous single-particle measurements.
