Luminescence lifetime thermometry with Mn³⁺–Mn⁴⁺ co-doped nanocrystals

Abstract

Luminescence thermometry is one of the most promising techniques of temperature sensing which provides fast and accurate readout in the non-contact regime.

Triplet‐State Position and Crystal‐Field Tuning in Opto‐Magnetic Lanthanide Complexes: Two Sides of the Same Coin

“…The differences between the three complexes are even more significant when assessing the performance of the compounds as luminescent thermometers (Figure , for calculations see the Supporting Information). When selecting a luminescent thermometer, one of the more robust thermal parameter to consider is the luminescence lifetime ( τ ) of the energy level from which the transition associated with the monitored emission stems . Although usually requiring a rather sophisticated detection system, this parameter allows to overcome the shortcomings related with non‐ratiometric intensity‐based methods (e.g., intensity and concentration variations, along with power fluctuations of the excitation source) .…”

Optical Vacuum Sensor Based on Lanthanide Upconversion—Luminescence Thermometry as a Tool for Ultralow Pressure Sensing

“…The remote optical determination of pressure and temperature take benefits of rapid and noninvasive detection over the use of traditional manometers and thermometers, which require physical contact with the inspected system . The optical manometers and thermometers are usually based on the inorganic materials doped with lanthanide (Ln 2+/3+ ) and/or d‐block metal ions . Photoluminescence characteristics of such probes are usually strongly affected by changes in pressure and/or temperature .…”

“…The optical manometers and thermometers are usually based on the inorganic materials doped with lanthanide (Ln 2+/3+ ) and/or d‐block metal ions . Photoluminescence characteristics of such probes are usually strongly affected by changes in pressure and/or temperature . In the case of pressure, the measured spectroscopic parameter is usually a pressure‐induced line shift, i.e., spectral shift of the emission bands of Cr 3+ (ruby) or Sm 2+ .…”

The Impact of Cr3+ Doping on Temperature Sensitivity Modulation in Cr3+ Doped and Cr3+, Nd3+ Co-doped Y3Al5O12, Y3Al2Ga3O12, and Y3Ga5O12 Nanothermometers

“…One of the most promising one, relies on exploiting transition metal (TM) ions, whose highly temperature dependent emission is referred to emission of barely temperature dependent lanthanides ions (Marciniak et al, 2017a; Drabik et al, 2018; Elzbieciak et al, 2018; Kniec and Marciniak, 2018; Marciniak and Trejgis, 2018; Trejgis and Marciniak, 2018). Materials which could be applied as real time temperature sensors in biomedicine, must also accomplish some other important requirements like sufficient sensitivity to temperature changes, high stability, low cytotoxicity (Brites et al, 2012; Jaque and Vetrone, 2012; Benayas et al, 2015) and operation in spectral range of optical transparency windows of biological tissues (Anderson and Parrish, 1981; Jaque and Jacinto, 2016).…”
