“…It is clearly evident from the intensity profile and the radiative life time of the transition electrospun nanostructures [47]. The radiative parameters reported for neodymium tartrate trihydrate [48] were found to be of the order of micro-seconds, as the states were usual excited states with less life times and subsequently undergo spontaneous emission in a very short time. However in our case the radative parameters turned out to be of the order of milli-seconds, which is very large comparatively and hence the states act as meta stable states.…”

This study presents the hydrothermal synthesis of holmium bi-tartrate trihydrate single crystals.The crystal structure and morphology were determined using single crystal X-ray analysis andfield emission scanning electron microscopy, respectively. Fourier transform infrared spectroscopywas employed to identify the ligand phase. The thermal stability was assessed through differentialscanning calorimetry. The effect of ligand on the incorporated paramagnetic center is discernedby reckoning the magnetic moment of the same. Judd-Ofelt theory was utilized to analyze opticaltransitions and calculate excited state properties. The complex exhibited violet and red emissions,attributed to ligand-based and metal-based luminescence , respectively. The absence of antennaeffect was due to a significant energy gap between the resonance energy state, 5S2 of the Ho(III) ionand the triplet state of the coordinated tartrate ligand. The synthesized MOF’s prolonged radiativelifetime holds promise for laser technologies and environmental monitoring applications.

A new 3D metal-organic framework {[Nd 2 L 2 ]•2NH 2 (CH 3 ) 2 •3H 2 O} (Nd-MOF) was successfully established via a solvothermal method with Nd 3+ ion and 5-(bis(4-carboxybenzyl)amino) -isophthalicacid (H 4 L), and has also been characterized by X-ray diffraction, powder X-ray diffraction (PXRD), IR and photoluminescence(PL)spectrum. The neodymium ions are free of coordinated solvents, and the Nd-MOF exhibits strong near-infrared (NIR) uorescence. Besides, its NIR uorescence property shows low temperature resistance, which is favorable for being used in the low temperature environment.
