“…This was mainly because the addition of rare-earth complexes improved the fluidity of the melt and reduced the melt viscosity of the blend, which greatly increased the elongation at break of the films. Zhao et al [30] synthesized a series of thiophene trifluoropyruvate (HTTA), terephthalic acid (TPA), and Phen (III) complexes with the thermal reflux method. Through the elemental, infrared spectroscopy, scanning electron microscopy, and thermal stability analyses, the new Eu(TPA)(TTA)Phen and Eu 2 (TPA)(TTA) 4 Phen 2 complexes were characterized.…”

As new fluorescent materials, light wavelength conversion materials (light conversion agents) have attracted increasing attention from scientific researchers and agricultural materials companies due to their potential advantages in efficiently utilizing solar energy and increasing crop yield. According to the material properties, the light conversion agents can be divided into fluorescent dyes, organic rare-earth complexes, and inorganic rare-earth complexes. The current researches indicates that the fluorescent dyes have relatively high production costs, poor light stability, difficult degradation processes, and easily cause pollution to the ecological environment. The organic rare-earth complexes have short luminescence times, high production costs, and suffer from rapid decreases in luminescence intensity. Compared with fluorescent dyes and organic rare-earth complexes, although rare-earth inorganic complexes have high luminous efficiency, stable chemical properties, and better spectral matching performance, the existing inorganic light conversion agents have relatively poor dispersibility in agricultural films. According to the research on light conversion agents at home and abroad in recent years, this paper first introduces the three common light conversion agents, namely fluorescent dyes, organic rare-earth complexes, and inorganic rare-earth complexes, as well as their uses in agricultural films and their mechanisms of light conversion. At the same time, the preparation methods, advantages, disadvantages, and existing problems of various light conversion agents are classified and explained. Finally, we predict the development trends for light conversion agents in the future by considering six aspects, namely efficiency, cost, compatibility with greenhouse films, light matching, and light transmittance, in order to provide a reference for the preparation of stable and efficient light conversion agent materials.

A series of novel luminescent amino acid-rare earth complexes (denoted as Eu(L/D-SA) 3 -Phen) have been successfully synthesized. Using stearoyl alanine (denoted as SA) with different optical rotations as the first ligand and 1,10-phenanthroline (Phen) as the second ligand, the products were prepared by solution chemical reaction. Fourier transform infrared spectrometer (FT-IR), nuclear magnetic resonance spectroscopy ( 1 H NMR), x-ray diffraction (XRD), scanning electron microscope (SEM), ultraviolet and visible spectrum (UV) and photoluminescence spectroscopy were used to characterize the properties of Eu(L/D-SA) 3 -Phen. FT-IR, 1 H NMR and XRD indicate that ligand SA and Phen were prepared and successfully combined with Eu 3+ ions. SEM analysis shows relatively uniform morphological structure. Eu(L/D-SA) 3 -Phen exhibit a typical luminescence emission peak at 614 nm. In addition, the lifetimes of Eu(L/D-SA) 3 -Phen are in scale of millisecond. The relationship between fluorescence intensity of Eu(L/D-SA) 3 -Phen and the optical rotation of ligand SA has been studied and discussed. Based on the results, Eu(L/D-SA) 3 -Phen have excellent luminescent performance and possess potential application as luminescent materials.
