The powder X-ray diffraction technique was used to analyze the phases of all prepared borates. The FTIR technique was used to examine the bond structure of K2Al2B2O7. At room temperature, a spectrofluorometer was used to examine the photoluminescence characteristics of the prepared phosphors. K2Al2B2O7:Pb2+ was found to have emission and excitation bands at 373 and 271 nm, respectively. An extensive investigation was conducted on the correlation between emission intensity and Pb2+ content for K2-xPbxAl2B2O7. Consequently, 0.01 mol Pb2+ was found to be the optimal concentration in K2Al2B2O7. Eventually, it was found that the Stokes shift of the prepared material K2Al2B2O7:Pb2+ is 10,090 cm(-1) using the excitation band at 271 nm and the emission band at 373 nm. As a result of this investigation, a brand-new UVA radiation-emitting material has been established.eninfo:eu-repo/semantics/closedAccessaluminum borateluminescenceX-ray diffractionPb2+ ionArticle10.1007/s10812-024-01766-02-s2.0-851974909096493Q464591WOS:001263317000003N/A
