The present paper focuses on the development of novel smart fabrics having warning photoluminescent properties that keep light emitting for a period of time in the absence of an illumination source. Phosphorescence commonly brings added value for safety enhancement. Herein, we introduce a textile material coated with a photoluminescent layer. Dysprosium-and europium-doped strontium aluminate phosphor were admixed with a mixture of an adhesive binder and distilled water to afford the pigment−binder formula which was then applied directly onto wool fabric using a spray-coating technique. Results indicated that the optimal excitation wavelength of the coated fabric occurred at 365 nm, and an emission peak was also observed at 517 nm. A homogeneous phosphorescent layer was assembled on the surface of the wool fabric relying on the pigment concentration existing in the pigment−binder formula. This coated layer represents a substantial development of greenish-yellow, bright white, turquoise, and off-white colors as described by the CIE Lab color space data under ultraviolet irradiation. The decay curves and lifetime of phosphorescence were investigated. The fluorescent optical microscopy results, energy dispersive X-ray analysis, photoluminescence spectroscopic data, scanning electron microscopy images, and elemental mapping are described. The comfort properties of treated wool fabrics were evaluated by studying their stiffness and air permeability.

Soda lime phosphate bioglass-ceramics with incorporation of small additions of TiO2 were prepared in the metaphosphate and pyrophosphate region, using an appropriate two-step heat treatment of controlled crystallization defined by differential thermal analysis results. Identification and quantification of crystalline phases precipitated from the soda lime phosphate glasses were performed using X-ray diffraction analysis. Calcium pyrophosphate (beta-Ca2P2O7), sodium metaphosphate (NaPO3), calcium metaphosphate (beta-Ca(PO3)2), sodium pyrophosphate (Na4P2O7), sodium calcium phosphate (Na4Ca(PO3)6) and sodium titanium phosphate (Na5Ti(PO4)3) phases were detected in the prepared glass-ceramics. The degradation of the prepared glass-ceramics were carried out for different periods of time in simulated body fluid at 37 degrees C using granules in the range of (0.300-0.600 mm). The released ions were estimated by atomic absorption spectroscopy and the surface textures were measured by scanning electron microscopy. Evaluation of in vivo bioactivity of the prepared glass-ceramics was carried through implanting the samples in the rabbit femurs. The results showed that the addition of 0.5 TiO2 mol% enhanced the bioactivity while further increase of the TiO2 content decreased the bioactivity. The effect of titanium dioxide on the bioactivity was interpreted on the basis of its action on the crystallization process of the glass-ceramics.
