Novel blue-light-emitting materials based on ZnO and 2, 2′-bithiophene-5, 5′-dicarboxylic acid (DTDA), 4′, 3 ″-dipentyl-5, 2′: 5′, 2 ″: 5 ″, 2‴-quaterthiophene-2, 5‴- dicarboxylic acid (QTDA) have been prepared. The hybrid materials show that the PL λmax are at 450 and 425 nm for DTDA–ZnO and QTDA–ZnO, respectively.
