“…1 , shows the presence of a monoclinic SrAl 2 O 4 phase with P 21 , which matches with JCPDS file No. 34–0379 [ 19 ]. The addition of Ce 3+ (ionic radius 0.101 nm) ions in the crystal lattice, with a similar radius of Sr 2+ (ionic radius) 0.126 nm) , has not modified the crystal structure [ 20 ] which was evident from the peak of the XRD spectra [ 21 ].…”

“…Rare earth metal (REM) ions are emerging as one of the most precious materials because of their extensive use in manufacturing magnets, memory devices, and batteries. , Among different REMs, dysprosium (Dy) finds widespread modern applications as alloys for neodymium-based magnets, phosphor, halide discharge lamps, wind turbines, rechargeable NiMH batteries, and catalysts . Moreover, Dy(III)-nickel composite is frequently used in the control rods of nuclear reactors since it can rapidly absorb accelerated neutrons and does not swell/shrink when bombarded with neutrons for long periods .…”

“…With the help of a light source to excite luminescent materials, the traps can be charged, while the luminescent contents can be charged by exposure to light. 15 Thus, as time goes on, the crystals continue to generate light by prolonging the emission time period after the light source is turned off. There are a variety of persistent photoluminescent compounds available on the market with different color emissions.…”

“…Strontium aluminum oxide (SAO) crystals and divalent europium energy traps are key components of the long-lasting phosphorescence process. With the help of a light source to excite luminescent materials, the traps can be charged, while the luminescent contents can be charged by exposure to light . Thus, as time goes on, the crystals continue to generate light by prolonging the emission time period after the light source is turned off.…”

A simple inorganic/organic nanocomposite was used to generate long-lasting phosphorescent pebbles for easy commercial manufacturing of smart products. An organic/inorganic nanocomposite was made from low-molecular-weight unsaturated polyester and rare-earth-activated strontium aluminum oxide nanoparticles doped with europium and dysprosium. The polyester resin was mixed with phosphorescent strontium aluminate oxide nanoparticles and methylethyl ketone peroxide as a cross-linking agent to create a viscous mixture that can be hardened in a few minutes at room temperature. Before adding the hardener catalyst, the phosphorescent strontium aluminate nanoparticles were dispersed throughout the polyester resin in a homogeneous manner to ensure that the pigment did not accumulate. Long-lasting, reversible luminescence was shown by the photoluminescent substrates. The emission was reported at 515 nm upon exciting the pebble at 365 nm. In normal visible light, both blank and luminescent pebbles had a translucent appearance. As a result of UV irradiation, the photoluminescent pebbles produced an intense green color. The three-dimensional CIE Lab (International Commission on Illumination) color coordinates and luminescence spectra were used to investigate the color changing characteristics. Photophysical characteristics, including excitation, emission, and lifetime, were also investigated. Scanning electron microscopy, wavelength-dispersive X-ray fluorescence spectroscopy, and energy-dispersive X-ray analysis were employed to report the surface morphologies and elemental content. Without impairing the pebbles’ original physico-mechanical characteristics, the pebbles showed improved superhydrophobic activity. The current simple colorless long-lasting phosphorescent nanocomposite can be applied to a variety of surfaces, like ceramics, glassware, tiles, and metals.
