“…Recently, Cortecchia et al found that a significant deformation of the Pb − X bond length and the X − Pb − X bond angle can result in broadened PL spectra for the two perovskites, (NBT) 2 PbI 4 [71] and (EDBE)PbI 4 [72] (NBT = n-butylammonium and EDBE = 2,2-(ethylenedioxy)bis(ethylammonium)) [73]. …”

“…Photodetection techniques have demonstrated many important applications in a variety of fields or occasions, including medical X-ray imaging, ubiquitous visible light cameras, nearinfrared medical imaging and short-wave infrared surveillance and machine vision [1][2][3][4][5]. Current photodetection relies primarily on conventional semiconductor materials with an appropriate bandgap, capable of transducing photons with different energies into electrical signals for subsequent processing, image reconstruction and storage.…”

Compared to their conventional three-dimensional (3D) counterparts, two-dimensional (2D) halide perovskites have attracted more interests recently in a variety of areas related to optoelectronics because of their unique structural characteristics and enhanced performances. In general, there are two distinct types of 2D halide perovskites. One represents those perovskites with an intrinsic layered crystal structure (i.e. MX 6 layers, M = metal and X = Cl, Br, I), the other defines the perovskites with a 2D nanostructured morphology such as nanoplatelets and nanosheets. Recent studies have shown that 2D halide perovskites hold promising potential for the development of new-generation photodetectors, mainly arising from their highly efficient photoluminescence and absorbance, color tunability in the visible-light range and relatively high stability. In this chapter, we present the summary and highlights of latest researches on these two types of 2D halide perovskites for developing photodetectors, with an emphasis on synthesis methods, structural characterization, optoelectronic properties, and theoretical analysis and simulations. We also discuss the current challenging issues and future perspective. We hope this chapter would add new elements for understanding halide perovskite-based 2D materials and for developing their more efficient optoelectronic devices.

“…Binary lead chalcogenides are important semiconductors that have attracted attention during the last sixty years. These compounds, and solid solutions based on them, are well known functional materials, which have found wide use as IR sensors (PbS, PbSe) [1][2][3][4] and in thermoelectric devices (PbTe) operating in the middle temperature range [5][6][7][8][9]. An active study of the functional properties of these phases began in the 50's of the 20 th century [4,13] and continues to this day, as confirmed by the large number of investigations published over the last years.…”

Temperature can be used as clinical marker for tissue metabolism and the detection of inflammations or tumors.The use of magnetic resonance imaging (MRI) for monitoring physiological parameters like the temperature noninvasively is steadily increasing.I nt his study,w ep resent ap roof-ofprinciple study of MRI contrast agents (CA) for absolute and concentration independent temperature imaging. These CAs are based on azoimidazoles ubstituted Ni II porphyrins,w hich can undergo Light-Driven Coordination-Induced Spin State Switching (LD-CISSS) in solution. Monitoring the fast first order kinetic of backisomerisation (cis to trans) with standard clinical MR imaging sequences allows the determination of half-lives,t hat can be directly translated into absolute temperatures.Different temperature responsive CAswere successfully tested as prototypes in methanol-based gels and created temperature maps of gradient phantoms with high spatial resolution (0.13 0.13 1.1 mm) and low temperature errors (< 0.22 8 8C). The method is sufficiently fast to recordt he temperature flowf rom aheat source as afilm.
