Moscovite samples display spectral CL bands at 285 and 560 nm but only when the electron-beam is directed along the (0 1 0) orientation and not along the (0 0 1) orientation. The Tl⁺ versus K⁺ cation isomorphism anchors the luminogenous hydrous thallium–manganese complexes to the potassium-bearing aluminosilicate surfaces under analyses. The CL emission bands at 285 and 560 nm of these complexes together with the EDS detection of thallium are a fast analytical measurement detecting the presence of thallium in further studies involving this toxic element.]]> Sat 24 Mar 2018 07:26:58 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37730 Mon 29 Jan 2024 17:46:06 AEDT ]]>
