“…[23] They outperform than other nanoparticles in terms of luminescence qualities, decay time, illumination time, brightness, and longevity, and also enable the incorporation of adjustable plasmonic features like tunable wavelength. [108] Recently, a lot of work has been put into increasing the luminescence intensity in down-conversion and refining luminous materials to increase the potential for high-quality imaging. Once the downconversion nanomaterials are excited to a certain energy level, nonradiative processes often squander a fraction of the excitation energy, until a luminescence-generating resonance level is reached, hence causing down-conversion luminescence via Stokes shift, where the absorbed photons have a short wavelength, while longer wavelength and lower energy exhibited in the emitted photon.…”

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.

“…Recent years have seen a surge in interest in rare-earth semiconductors exhibiting UC luminescence due to their numerous uses in photonics, biological imaging, and photovoltaics [ 1 , 2 , 3 , 4 , 5 ]. The most efficient UC luminescence emission is based on Er ions in combination with Yb ions as sensitizers, which exhibits large anti-Stokes shifts, long up-conversion luminescence lifetimes, and superior photostability [ 6 , 7 , 8 ]. Fluorides, such as NaYF 4 , NaGdF 4 , and NaLuF 4 , are frequently utilized as the host matrix for the study of UC luminescence due to their high chemical stability and low phonon energy [ 9 , 10 , 11 , 12 , 13 ].…”

In this work, Li+-doped NiO:Yb,Er thin films are obtained via pulsed laser deposition. It was found that the films exhibit high transparency in the visible region and clearly red up-conversion luminescence under 980 nm excitation. Doping with Li+ can adjust the up-conversion emission intensity of the films. Moreover, all the films have p-type conductivity with a single activation energy of around 360 meV. The sheet resistivity of the films can be improved through changing the doping concentration of Li+ ions. Taken together, 5% is the best doping concentration for the potential application of this kind of film.
