Characterization and laser properties of lanthanum magnesium hexa-aluminate activated by neodymium and chromium

Combustion Synthesis of Some Cr3+-Activated Aluminate Phosphors

“…It had been shown to be a [32][33][34][35][36][37]. In the last four decades, there has been much interest in LMA doped with different ions because they have suitable optical properties for IR laser [38] and for their use as phosphor [39]. In particular, there has been high interest in LMA crystal doped with 3d elements [40].…”

Role of La 5p in Bulk and Quantum-Confined Solids Probed by the La 5p54f1 3D1 Excitonic Final State of Resonant Inelastic X-ray Scattering

“…The f-block rare-earth (RE) elements (La−Lu) are present in many compounds with a wide range of applications, including phosphors, 1−3 scintillators, 4,5 superconductors, 6,7 and solidstate lasers 8,9 as well as catalysts. 10−13 The RE elements are generally considered to be atomically localized species, mainly caused by their highly localized frontier orbitals.…”

“…The f-block rare-earth (RE) elements (La–Lu) are present in many compounds with a wide range of applications, including phosphors, − scintillators, , superconductors, , and solid-state lasers , as well as catalysts. − The RE elements are generally considered to be atomically localized species, mainly caused by their highly localized frontier orbitals. − This is in strong contrast to actinides, where the 5f orbital is spatially more diffused and evidenced to be involved in covalent bond formation. − However, recently both theoretical and experimental work suggested that the REs contribute to band formation and screening. − Do the 4f-block REs participate in chemical bonding, and which orbitals contribute to covalency? How can this be linked to material functionality?…”
