“…Here, we focus on the need to differentiate between observed emission intensity and actual transition probability. The latter is determined exclusively by electron structure, while the former is affected by several parameters . Using the emission intensity as a single parameter in, for example, a binding study thus potentially leads to significant errors.…”

Lanthanide luminescence has been treated separate from molecular photophysics, although the underlying phenomena are the same. As the optical transitions observed in the trivalent lanthanide ions are forbidden, they do belong to the group that molecular photophysics has yet to conquer, yet the experimental descriptors remain valid. Herein, the luminescence quantum yields (ϕ lum ), luminescence lifetimes (τ obs ), oscillator strengths (f), and the rates of nonradiative (k nr ) and radiative (k r ≡ A) deactivation of [Eu(H 2 O) 9 ] 3+ were determined. Further, it was shown that instead of a full photophysical characterization, it is possible to relate changes in transition probabilities to the relative parameter A rel , which does not require reference data. While A rel does not afford comparisons between experiments, it resolves emission intensity changes due to emitter properties from intensity changes due to environmental effects and differences in the number of photons absorbed. When working with fluorescence this may seem trivial; when working with lanthanide luminescence it is not.

“…[46] In this context, numerous published literatures have reported the excited-state dynamics of lanthanides. [47][48][49] Sensitizer ligands offer effective energy absorption capabilities for luminophores, and their sensitization pathway comprises both forward and backward energytransfer processes in the excited state. Various energy transfer pathways are better presented diagrammatically in Figure 11d.…”

Recent chronological breakthroughs in materials innovation, their fabrication, and structural designs for disparate applications have paved transformational ways to subversively digitalize infrared (IR) thermal imaging sensors from traditional to smart. The noninvasive IR thermal imaging sensors are at the cutting edge of developments, exploiting the abilities of nanomaterials to acquire arbitrary, targeted, and tunable responses suitable for integration with host materials and devices, intimately disintegrate variegated signals from the target onto depiction without any discomfort, eliminating motional artifacts and collects precise physiological and physiochemical information in natural contexts. Highlighting several typical examples from recent literature, this review article summarizes an accessible, critical, and authoritative summary of an emerging class of advancement in the modalities of nano and micro‐scale materials and devices, their fabrication designs and applications in infrared thermal sensors. Introduction is begun covering the importance of IR sensors, followed by a survey on sensing capabilities of various nano and micro structural materials, their design architects, and then culminating an overview of their diverse application swaths. The review concludes with a stimulating frontier debate on the opportunities, difficulties, and future approaches in the vibrant sector of infrared thermal imaging sensors.
