| dc.description.abstract | In this study, cathodoluminescence (CL) spectroscopy at direct current and alternating current under the sample temperature condition of 40-293 K using different modulation frequencies is presented for alkali feldspar from the Dartmoor granite (UK). These feldspars contain strain-controlled lamellar crypto-and microperthites that are cross-cut by strain-free deuteric microperthites. The CL spectra of the alkali feldspar at room and low temperature confirm that the observed emission peaked at ∼460 nm could be associated with Al-O--Al or Ti impurity centers, yellow emission ∼560 nm could be associated with the presence of the centers such as radiation-induced defect centers, and ∼756 nm emission could be associated with the Fe3+ impurity center on T1 and T2 sites. The consequence of their association is to produce different luminescence properties such as intensity, peak wavelength, and band shape. © 2014 Copyright Taylor & Francis Group, LLC. | |
