The luminescence study of LiGa5(1−x)O8:5xCr3+ coumpounds

Description

Infrared luminescent materials have evoked much attention from chemists and material scientists. Although substantial progress is made in materials design, the luminescent mechanism remains ambiguous in the complex structures, presenting major barriers to developing novel infrared luminescent materials. Herein, this study aims to deliberate a complete discussion on infrared phosphors with concentration-induced hetero-valent partial-inverse occupation in LiGa5(1−x)O8:5xCr3+.  Furthermore, unexpected two-center Cr3+ emissions and the Cr–Cr pair emission are observed at high Cr concentrations. Variation between the zero-phonon line and N-line at different temperatures is demonstrated. Finally, the structural and luminescent properties are comprehensively discussed, providing the origin of the unexpected Cr2 emission. This study not only provides insight into the hetero-valent partial-inverse occupation process in inorganic materials but also sheds light on developing novel infrared luminescent materials.

In that dataset, raw data of excitation and emission spectra, temperature-dependent, and high-pressure dependent photoluminescence and decay profiles are provided
