“…While SAO particles are uniformly distributed into the PLA matrix, some agglomerations of SAO particles are also present, and this may negatively affect the tensile properties. However, the relatively random distribution of SAO particles is favorable and helps the luminous SAO/PLA composite radiate green light after excitation [25].…”

We report luminous polylactic acid (PLA) composite prepared via a solvent casting method using different amounts of phosphor strontium aluminate (SrAl2O4: Eu2+ and Dy3+) (SAO). The reason for doing this is that the changes of fluorescence and mechanical properties in the composites with different SAO contents can be directly evaluated. The SAO particles should have a variety of excellent characteristics in the PLA matrix, among which dispersibility and compatibility are particularly important; so, they can be modified by 3-aminopropyltriethoxysilane (APS) to achieve the target characteristics. The results showed that the fluorescence and mechanical properties were affected by SAO addition. The mechanical properties significantly improved with 5 wt% SAO; further, addition had no impact. And the emission band of fluorescence and phosphorescence is just at the peak of 524 nm. The composites with 15 wt% SAO have the best fluorescence properties. The fluorescence decreased with further doping. Fluorescence decay curves with various amounts of SAO particles show a similar tendency as pure SAO particles; the speed of decrease in afterglow intensity was higher for the first 30 min. In addition, the detailed morphological scanning and study by scanning electron microscope (SEM) showed that the particles had good adhesion to the matrix. In conclusion, the concentration of SAO into the PLA matrix impacts the fluorescence and mechanical properties of a SAO/PLA composite material.

“…This material has excellent light response performance, with high initial brightness, long afterglow duration, and high conversion efficiency. Its application in the textile industry has attracted more and more attention [13][14][15][16]. The most remarkable feature of the luminescent materials contained in the textile is that it can release the stored light energy under dark conditions after absorbing any visible light for 10 min.…”

The smart fabric based on temperature-sensitive/light-sensitive dual-response is a functional fabric that can change color with temperature and emit green light in the dark after being excited by light. Prepared by silk-screen printing technology, it is made of temperature-responsive polymers, rare earth photosensitive paste, adhesives, thickeners, and other materials. When the temperature-responsive polymer is 10%, the rare earth photosensitive paste is 12%, and the adhesive is 25%, the printed cotton fabrics had the highest K/S value, the best abrasion resistance, and the best soaping color fastness. After 30 heating and cooling tests, the color depth and temperature-sensitive discoloration performance of the fabrics were still good. The fabric prepared by mixing orange and blue temperature-sensitive color change microcapsules and rare earth light response materials with different mass ratios can obtain continuous multi-color effect at 31-40℃. Under the excitation of 365 nm wavelength, the fabric appears the characteristic green light of SrAl2O4: Eu2+, Dy3+ luminescent materials. With the increase of temperature, the emission intensity increases first and then decreases. The luminance of the fabric after heating is obviously higher than that under the room temperature.

“…The flow chart of degrading PET and recycling luminescent materials is shown in Figure 1. Zhu et al 12 found that the glycolysis method could not only degrade the luminous polyester fibers rapidly but can also retain the crystal structure of the rare earth luminescent materials. However, the luminescent performance of the recovered luminescent materials was poor.…”

To alleviate the wastage of resources and environmental pollution caused by waste luminous polyester fibers, glycolysis was found rapidly to degrade luminescent polyester fibers and assist in recovering luminescent materials from the fibers. However, the luminescent performance of recycled luminescent materials is poor. To improve the performance of recovered luminescent materials, this study employs the recovery rate of luminescent materials, initial brightness, and recovery rate of Bis (2-hydroxyethyl) terephthalate as performance indexes. The present study aims at optimizing the alcoholysis process by influencing factors such as the amount of catalyst, amount of ethylene glycol added, and reaction temperature to improve the luminous performance, and explores the mechanism of alcoholysis reaction in the recovery process of luminescent materials. The results showed that, when the catalyst content is 0.1 g, the mass ratio of polyethylene terephthalate:ethylene glycol is 1:10, the reaction temperature is 170°C for 4 hours, the Bis (2-hydroxyethyl) terephthalate conversion rate reaches 61.92%, the recovery rate of luminescent materials reaches 92.53%, and the initial brightness is as high as 5.607 cd/m2.
