- Description
- Eu3+-activated La2Ba3B4O12 (LBBO) phosphor was synthesized by the solid-state reaction method. LBBO phosphors characterized by structural analysis (X-ray diffraction), including refinement parameters and crystallite size, morphological analysis by (Scanning Electron Microscopy and Transmission Electron Microscopy). Photoluminescence (PL) studies of synthesized phosphors monitored in the range of 450-675 nm for the LBBO phosphor doped with Eu3 +. An excitation peak was found at 254nm and several sharp emission peaks were found around 466, 541, 588, 593, 613, and 626nm with high intensities. The crystallite size of the Eu3 +-doped LBBO phosphor was around 126nm. It is found that the intense emission peak is in the red region. The detailed processes involved and a possible mechanism for the PL are studied and discussed. The phosphor can also be used in forensic science to detect fingerprints. 2021 Elsevier Ltd All rights reserved.
