“…Therefore, an increase in interaction volume (which effectively determines the generation of light inside the phosphor) with an increase in electron energy brings about an increase in the CL brightness of LuBO 3 :Eu 3 + particles. [34] Due to their strong low-voltage CL intensity and improved chromaticity, calcite-type LuBO 3 …”

Rhombohedral-calcite and hexagonal-vaterite types of LuBO(3):Eu(3+) microparticles with various complex self-assembled 3D architectures have been prepared selectively by an efficient surfactant- and template-free hydrothermal process for the first time. X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectrometry, transmission electron microscopy, high-resolution transmission electron microscopy, selected area electron diffraction, photoluminescence, and cathodoluminescence spectra as well as kinetic decays were used to characterize the samples. The pH, temperature, concentration, solvent, and reaction time have a crucial influence on the phase formation, shape evolution, and microstructure. The reaction mechanism is considered as a dissolution/precipitation process; it is proposed that the self-assembly evolution occurs by homocentric layer-by-layer growth. Under UV excitation and low-voltage electron beam excitation, calcite-type LuBO(3):Eu(3+) particles show a strong orange emission corresponding to the (5)D(0)-->(7)F(1) transition of Eu(3+) whereas vaterite-type LuBO(3):Eu(3+) particles exhibit a strong red emission with much higher R/O values (that is, chromatically redder fluorescence than that of crystals grown from a direct solid-state reaction). The tunable luminescent properties have potential applications in fluorescent lamps and field emission displays.

“…According to the selection rules, allowed electric dipole transitions in system with no inversion of symmetry (which is the case with Y 2 O 3 :Eu 3+ system) are those for which J ≤ 6. The transitions arising from magnetic dipole transitions are those for which J = 0, ±1 but the transition J = 0 → J = 0 is forbidden [27,28].…”
