Synthesis and Photoluminescence study of Strontium salts with 2-Methyl-8-Hydroxyquinoline and 8-Hydroxyquinoline
View through CrossRef
Abstract
The pure green and turquoise green-emitting organometallic complex of strontium(II) with 8-Hydroxyquinoline and 2-methyl-8-hydroxyquinoline were synthesized by using Co-precipitation method. The structure of Sr(8-Hq)2 and Sr(2-Me-8Hq)2 was studied with Fourier transform infrared spectroscopy, and the vibrational peak of the Sr-O bond was found at 503 cm−1 and 499 cm−1 respectively. The X-Ray diffraction spectra are taken and compared with XRD data of raw materials to confirm the formation of the complex. Further UV-Absorption was studied, and the optical band gap is 2.813eV and 2.852eV, respectively, by using Taucs plot method. The photoluminescent study carried out in solution medium, and the emission wavelength found at 526nm and 509nm, and the color is confirmed using the CIE plot method, and the emission color is pure green and turquoise green. The complex may have significant applications as emitters in organic optoelectronic devices.
