Description
Summary:This paper includes the synthesis of bluish-green light emitting metal based hydroxyl quinoline complexes namely, Mgq2, Baq2 and MgxBa(1-x)q2 (Mg: Magnesium, Ba: Barium, q: 8-hydroxy quinoline, x = 0.1, 0.2,….0.9) by simple precipitation method at different values of pH and stoichiometry. It’s noteworthy to state that we are the first one to report novel complexes based on Ba (Baq2 and Mg0.5Ba0.5q2). The inquisition of these complexes was carried out to probe structural, photo physical and photometric parameters by FTIR, photoluminescence (PL) spectra and 1931 CIE colour calculator, respectively. These investigations reveal that pH value and stoichiometry have feeble effects on the emission wavelength and intensity. Investigations further reveal that among all the synthesized complexes, Baq2 (at pH 6.5) emits intense blue light in various environments. Thus, barium based quinoline complexes have the potential to sustain their emission features in solid state as well as in acidic and basic medium-one of the characteristic features which are highly essential for the fabrication of OLEDs by vacuum as well as solution techniques.
