Ionization energy of lanthanum

WebScintillating materials that convert ionizing radiation into low-energy photons hold great potential for radiation detection, nondestructive inspection, medical radiography, and space exploration. However, organic scintillators are characterized by low radioluminescence, while bulky inorganic scintillators are not suitable for the development of flexible detectors. WebLanthanum oxide is a white solid that can be prepared by direct reaction of its constituent elements. Due to the large size of the La 3+ ion, La 2 O 3 adopts a hexagonal 7-coordinate structure that changes to the 6-coordinate structure of scandium oxide (Sc 2 O 3) and yttrium oxide (Y 2 O 3) at high temperature.
