Abstract

Spectroscopic exploration of CoO doped lithium borophosphate glass systemhas been studied. Asystematic investigation on characterization, XRDstudies and spectroscopic properties (viz., optical absorption, infrared, and ESR) has been carried out. The X-ray diffraction confirms that the samples prepared were of amorphous nature. The optical absorption spectra of the present glass system exhibited three clearly resolved absorption bands at 530nm, 580nm and 625nm. The bands are attributed due to 4T1g(4F)→2T2g(2H), 4T1g(4P)→4A2g(4F), 5T2g-5Eg. FTIR spectra of CoO doped glasses has indicated stretching symmetry of various bands B – O, P – O, O-H, H-O-H, PO3 etc. The g-value is found to be minimum at 0.3mol% of CoO. The LBPCo glass doped with 0.3mol% of CoO is found to be ideal candidate for photoluminescence and electrical applications.
