Improving the temperature-sensing performance of the SrZn_0.33Nb_0.67O₃:Pr³⁺ phosphor via Ga³⁺ doping

Abstract

Optical thermometry offers promising application in the microelectronic and biomedical fields, as well as fire pre-warning systems. In this research, Pr3+ activated SrZn0.33Nb0.67O3 phosphors were successfully prepared via solid-state reactions....

Green Emission in Thermally Stable Er3+ Doped Lead-Free Perovskite Phosphor for Solid-State Lighting and Optical Thermometry Applications

“…Remarkably, the decay behavior of CaTiO 3 : 0.5 % Er 3+ phosphor is effectively described by a third-order exponential decay model (Exp Dec 3). The governing equation for Exp Dec 3 is denoted as equation ( 6) [52]:…”

Polarity-Independent Temperature-Induced Reversible Fluorescence Switching of Organic Nanoparticles: Application to Intracellular Temperature Imaging

“…Such measurements may sometimes give erroneous values, as at times, they get affected by factors such as surroundings, distance, positioning, etc. 8,9 On the other hand, fluorescence thermometry could be an excellent choice in this case, as the steady-state fluorescence technique is highly sensitive, inherently multidimensional, and easy to interpret and offers rapid feedback. 10,11 The multidimensional nature of fluorescence is highly beneficial to obtain information for distinguishing two or more analytes in complex matrixes.…”

“…On the contrary, in the case of noncontact temperature measurement, the surface temperature is measured by the optical analysis of the infrared radiation emitted. Such measurements may sometimes give erroneous values, as at times, they get affected by factors such as surroundings, distance, positioning, etc. , …”
