“…The roughness and contact angle of LA 7 and LA 8 were marginally reduced when the quantity of LA nanoparticles was increased. Smart windows that can filter ultraviolet rays are a convenient way to protect humans from sunburn, erythema, and skin cancer [ 28 , 29 ]. Figure 8 displays the results of testing the ultraviolet protection properties of GLS@PET.…”

“…Due to their exceptional photostability, lanthanide aluminates (LAs) exhibit high reversibility. Inorganic phosphors have shown different emission colors such as SrAl 2 O 4 :Eu 2+ ;Dy 3+ as greenish emitter [ 27 ], CaMgSi 2 O 6 :Eu 2+ ;Dy 3+ as bluish emitter [ 28 ], and Y 2 O 2 S:Eu 3+ ;Mg 2+ ;Ti 4+ as reddish emitter [ 29 ]. These photochromic inorganic phosphors are among the most impressive colorants due to their efficient photoluminescence, persistent emissions (>10 h), and resistivity to light, heat and chemicals [ 30 , 31 ].…”

Development of Photoluminescent and Photochromic Polyester Nanocomposite Reinforced with Electrospun Glass Nanofibers

A polyester resin was strengthened with electrospun glass nanofibers to create long-lasting photochromic and photoluminescent products, such as smart windows and concrete, as well as anti-counterfeiting patterns. A transparent glass@polyester (GLS@PET) sheet was created by physically immobilizing lanthanide-doped aluminate (LA) nanoparticles (NPs). The spectral analysis using the CIE Lab and luminescence revealed that the transparent GLS@PET samples turned green under ultraviolet light and greenish-yellow in the dark. The detected photochromism can be quickly reversed in the photoluminescent GLS@PET hybrids at low concentrations of LANPs. Conversely, the GLS@PET substrates with the highest phosphor concentrations exhibited sustained luminosity with slow reversibility. Transmission electron microscopic analysis (TEM) and scanning electron microscopy (SEM) were utilized to examine the morphological features of lanthanide-doped aluminate nanoparticles (LANPs) and glass nanofibers to display diameters of 7–15 nm and 90–140 nm, respectively. SEM, energy-dispersive X-ray spectroscopy (EDXA), and X-ray fluorescence (XRF) were used to analyze the luminous GLS@PET substrates for their morphology and elemental composition. The glass nanofibers were reinforced into the polyester resin as a roughening agent to improve its mechanical properties. Scratch resistance was found to be significantly increased in the created photoluminescent GLS@PET substrates when compared with the LANPs-free substrate. When excited at 368 nm, the observed photoluminescence spectra showed an emission peak at 518 nm. The results demonstrated improved hydrophobicity and UV blocking properties in the luminescent colorless GLS@PET hybrids.

“…[6,7] The typical commercial afterglow phosphors are mainly inorganic oxides, such as Sr 2 MgSi 2 O 7 :Eu 2+ / Dy 3+ , SrAl 2 O 4 :Eu 2+ /Dy 3+ , Y 2 O 2 S:Eu 3+ / Mg 2+ /Ti 4+ , and Zn 3 Ga 2 Ge 2 O 10 : Cr 3+ . [9][10][11][12] Although they have fascinating properties, including high afterglow intensity and ultralong afterglow for several days, these compounds generally have high lattice energy and therefore require hightemperature (> 1000 °C) calcination to obtain the target product. Obviously, the high-temperature production process will undoubtedly cause serious energy consumption and bring a series of security risks.…”

Long afterglow luminescent materials have captured intense attention for their unique applications in biological imaging, photodynamic therapy, and optical anti-counterfeiting. However, achieving highly efficient and tunable ultralong afterglow emission in all-inorganic metal halides is an open challenge. Herein, Sb 3+ -doped hexagonal CsCdCl 3 metal halide is reported via hydrothermal reaction. Upon photoabsorption, the as-synthesized compounds exhibit dual-emission bands with a photoluminescence quantum yield (PLQY) of 59.6%, which can be attributed to the self-trapped exciton emission out of the strong electron-phonon coupling. After ceasing excitation of 365 nm, bright afterglow emission with the longest duration lasting up to 5000 s is witnessed in Sb 3+ -doped CsCdCl 3 . More importantly, the color-tunable and time-dependent ultralong afterglow emission is realized via regulating the doping concentration of Sb 3+ , which should be due to the trap electrons increase gradually under high doping concentration. Given this unusual afterglow emission characteristics, the optical anti-counterfeiting and information encryption are constructed based on as-synthesized compounds. These findings not only help further understand the tunable afterglow emission mechanism in all-inorganic metal halides, but also provide a new strategy for designing novel ultralong afterglow luminescent materials.
