Description

Band gap of LiInO2 is studied by a photoacoustic spectroscopy (PAS). LiInO2 is a candidate material for solar neutrino detection due to an inverse β--decay of 115In. LiInO2 samples synthesized by a sol gel method are confirmed to be the single phase of LiInO2 (the lattice constant: a=4.3141 Aa and c=9.3549 Aa, the space group: I41/amd) by a powder X-ray diffraction and their crystallinity is confirmed by a Raman scattering spectroscopy. The PAS spectra of LiInO2 show a knee at around 4.3 eV, suggesting the optical absorption related to the band gap of LiInO2. The band gap value of 4.3 eV evaluated by PAS is close to the optical band gap (4.4 eV) observed by an optical absorption method. (copyright 2006 WILEY-VCH Verlag GmbH and Co.
