Tunable luminescence of Eu3+/Tb3+-doped MgZrO3: from single doping to co-doping for anti-counterfeiting applications

MgZrO3 (MZO) has been extensively investigated for its electrical, structural, optical and catalytic properties in environmental applications. However, the fabrication of color-tunable MZO:0.10Tb3+, zEu3+ [z = 0.005, 0.010, 0.030, 0.050, and 0.070] nanophosphors and their potential applications in anti-counterfeiting i...

Synthesis and DFT Study of New Pyrano[3,2-c]Quinoline Derivatives for Antioxidant, Forensic, and Security Ink Applications

Abstract A series of heterocyclic derivatives incorporating the pyrano[3,2-c]quinoline-2,5-dione framework were successfully synthesized via nucleophilic substitution reactions of 6-ethyl-4-chloropyrano[3,2-c]quinoline-3-carbaldehyde 2 with several sulfur nucleophiles. Furthermore, aldehyde 2 underwent condensation rea...
