摘要：
The novel tetrakis beta-diketonate of lanthanum complexes M[La(acac)(4)] with a variety of cationic ligands, M = Li+, Na+ and K+ has been synthesized. The structural and optical characterizations of prepared complexes were carried out by FESEM, FTIR, UV-Vis and PL techniques. A transmittance at around 1600 cm(-1) was observed which corresponds to the ketonate group. The excitation spectra of the synthesized complexes show a broad peak in the range of 360-410 nm. Emission spectra were recorded by keeping excitation wavelength fixed at 390 nm. A good intensity emission peak due to O-2p -> La-5d transition of LaO8 was observed at 473 nm. The CIE chromaticity coordinates of all the complexes were observed in the blue region. It could be considered as promising phosphor for blue light emitting materials in OLEDs.
