“…Second-harmonic generation experiments are carried out between 1100 and 1700 nm and within the hysteresis loop of this compound. In the low-and high-temperature phases, our measurements indicate that the effective second-order nonlinear component (2) of this material is small, compared with α-quartz. However, in the high-temperature phase and…”

“…Notably, if the Kleinman's symmetry conditions hold, this material exhibits the same non-null nonlinear coefficient xvz (2) in both the HT and LT phases. [10] This makes it possible to directly compare the values of the second-order nonlinear properties of this compound in the HT and LT phases.…”

“…Hence, it is difficult to directly compare the secondorder nonlinear optical properties of this material in the LT and HT phases. Hereafter, we will demonstrate that, thanks to a procedure we will describe, we have been able to determine the value of xvz (2) for this compound in the LT and HT phases over a spectral range of 1.1-1.8 μm. In the LT phase and at 1.1 μm, the measured second-order optical susceptibility increases about two orders of magnitude, reaching a value xvz (2) = 2.7 ± 0.3 pm V -1 .…”

“…The modulation of the SHG signal recorded during the structural change of this compound provides an original mean to record the thermal hysteresis loop. [6] However, the recorded modulation of the SHG signal may be either due to the modification of the amplitude of xvz (2) or the index of refraction in the LT and HT phases. [11] In the HT phase, exciting the sample with nanosecond pulses centered at λ = 1.064 μm, xvz (2) was found to be ca.…”

Second-harmonic and terahertz generation is performed in the Rb 0.94 Mn[Fe(CN) 6 ] 0.98 ·0.3H 2 O Prussian-blue analogue. Second-harmonic generation experiments are carried out between 1100 and 1700 nm and within the hysteresis loop of this compound. In the low-and high-temperature phases, our measurements indicate that the effective second-order nonlinear component (2) of this material is small, compared with α-quartz.

The capacity to discern the highest temperature that an object is subjected to is a crucial diagnostic tool. Consequently, the pursuit of materials that enable the luminescence‐based investigation of the thermal history of an object with high sensitivity is of great importance from the functional applications standpoint. This study aims to present a multiparametric thermal history phosphor based on the luminescent coordination polymer [Eu(BTC)(H2O)6] [Eu(BTC)‐1, where H3BTC = 1,3,5‐benzenetricarboxylic acid]. The progressive dehydration that Eu(BTC)‐1 undergoes as a function of temperature increase in the 343–425 K range results in significant alterations in both the shape of the Eu3+ ions emission spectrum and the depopulation kinetics of their 5D0 level. Based on this occurrence, a thermal history phosphor with an unprecedentedly high relative sensitivity of 11.3% K−1 in ratiometric mode, and 1.8% K−1 in lifetime‐based mode, is developed. The outcomes of this research are expected to stimulate a wide interest in the exploitation of (porous) coordination polymer‐type materials for the development of thermal history phosphors.

focus on MOFs and hybridized MOFs for photonic applications including solid state lighting, [14][15][16] lasing, [17][18][19] nonlinear optics, [20,21] and phototherapy [22][23][24][25] has attracted a vast attention.The synthesis of MOFs requires both metal salts/clusters and organic linkers, which can be realized through conventional methods from room temperature to elevated temperatures and solvothermal conditions. In the case of solvothermal conditions, autoclaves are utilized to give extra pressure and better solubilities above boiling point of the solvent compared to refluxing at atmospheric pressure. Furthermore, mechanochemical synthesis, microwave-assisted synthesis, electrochemical synthesis, and sonochemical synthesis are also available. [26] It is noteworthy that topologies may vary when utilizing the same starting materials under different reaction conditions, which causes multiple combinations of starting materials with structural transformations and intriguing properties.Studies on MOFs for photonic applications are rapidly growing. In the field of solid state lighting materials based on MOFs, the emitting light is generated from combinations of inorganic metal nodes, organic linkers, and guest species showing enhanced stability and efficiency compared to pure inorganic or organic lighting materials. Optical and thermal stabilities are improved for micro-/nano laser devices based on MOFs compared to organic dye lasers. For phototherapy purposes, MOF-based cures need to additionally hybridize with organic polymers to be affordable in physiological environment and guest species with high photothermal conversion efficiency to enhance light absorption. As of applications for nonlinear optics based on MOFs displaying second harmonic generation (SHG) and third harmonic generation (THG), one focus is to construct non-centrosymmetric structures with appropriate coordination geometries supported by rigidly bridging organic linkers to possess second-order nonlinear optical (NLO) properties. [27] On the contrary, THG occurs in all materials showing much weaker NLO properties than SHG. [20,28] Herein, we concentrate on the very recent progresses for photonic MOFs in the following applications: 1) white solidstate lighting; 2) lasing; 3) nonlinear optics including SHG and THG; and 4) phototherapies including photodynamic therapy (PDT), photothermal therapy (PTT), and synergy effect. We discuss in detail the construction strategies and performances given by subcategories under each topic (Scheme 1).Materials of metal-organic frameworks (MOFs) in pure and hybridized forms showing photonic properties have received much attention during past years. Strategies to prepare photonic MOF-based materials are constantly used as follows: 1) designing of pure MOFs with intrinsic luminescent units such as organic linkers and/or lanthanide ions; 2) designing of hybrid MOF composites through encapsulation of extrinsic luminescent units such as organic dyes and/or inorganic nanospecies; and 3) designing of MOF-based composites ...
