dc.description.abstract | This study explores the structural and optical qualities of LaCa4O(BO3)3 (LACOB) phosphors doped with Eu3+,
Dy3+, and Tb3+ using a microwave-assisted sol-gel technique. It uncovers oxygen-related luminescence defects in
LACOB, highlighting emission peaks at 489 and 585 nm for Dy3+, a distinct sharp peak at 611 nm for Eu3+ in the
red spectrum, and a notable green emission for Tb3+ due to specific transitions. The photoluminescence (PL)
analysis indicates that luminescence is optimized through precise doping, leveraging dipole interactions, and
localized resonant energy transfer, which are influenced by dopant concentration and spatial configuration.
Temperature studies show emission intensity variations, particularly noticeable below 100 K for Tb3+ doped
samples, demonstrating the nuanced balance between thermal quenching and luminescence efficiency. This
temperature dependency, alongside the identified optimal doping conditions, underscores the potential of these
materials for advanced photonic applications, offering insights into their thermal behavior and emission
mechanisms under different conditions. | en_US |
