Synthesis, characterization and optical properties of a red organic–inorganic phosphor based on terephthalate intercalated Zn/Al/Eu layered double hydroxide

•Zn/Al/Eu layered double hydroxides intercalated by terephthalate were prepared.•Terephthalate anions are vertical to the layers of LDH.•Materials display much enhanced red luminescence and long lifetime.•An efficient energy transfer from terephthalate anions to Eu3+ takes place.•The optimal doping...
