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.　(C)　2022　American　Society　of　Civil　Engineers.
