Abstract
Recently, numerous studies have been carried out on the architecture of energy-efficient and environmentally friendly construction materials. In this study, there was studied the content of the strontium aluminate europium and dysprosium doping (SAEDD) on the properties of cement mortar. Portland cement was tested with 10%, 20%, and 30% SAEDD. The mortar cube specimens were then reacted with 5% hydrochloric (HCl) and nitric acid (HNO3) and with 5% of sodium sulfate (Na2SO4) to test the material's strength and chemical stability. The mortar samples that were supplemented with 20% of SAEDD gave the best luminescence that lasted ≤10 h. The compressive strength of the mortar cubes was improved by replacing cement with 20% of the SAEDD. In addition, X-ray diffraction (XRD), Fourier-transform infrared (FTIR) and energy dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) were used to study the performance of the SAEDD. From the results, the use of strontium aluminate (SrAlO4)-doped phosphors in dark mortar gave luminescence ≤10 h. This work could open a novel gateway in chemistry and novel aspects of chemical engineering, possibly helping to sustain green environments.
