Bi-doped compounds recently became the subject of an extensive research due to their possible applications as scintillator and phosphor materials. The oxides co-doped with Bi3+ and trivalent rare-earth ions were proposed as prospective phosphors for white light-emitting diodes and quantum cutting down-converting materials applicable for enhancement of silicon solar cells. Luminescence characteristics of different Bi3+-doped materials were found to be strongly different and ascribed to electronic transitions from the excited levels of a Bi3+ ion to its ground state, charge-transfer transitions, Bi3+ dimers or clusters, radiative decay of Bi3+-related localized or trapped excitons, etc. In this review, we compare the characteristics of the Bi3+-related luminescence in various compounds; discuss the possible origin of the corresponding luminescence centers as well as the processes resulting in their luminescence; consider the phenomenological models proposed to describe the excited-state dynamics of the Bi3+-related centers and determine the structure and parameters of their relaxed excited states; address an influence of different interactions (e.g., spin-orbit, electron-phonon, hyperfine) as well as the Bi3+ ion charge and volume compensating defects on the luminescence characteristics. The Bi-related luminescence arising from lower charge states (namely, Bi2+, Bi+, Bi0) is also reviewed.

This research presents the outcomes of diverse morphological and photoluminescence (PL) studies performed on Bi3+ ion–doped Ba3MoTiO8 phosphors prepared via the conventional solid‐state reaction method. Phase assessment was carried out via the X‐ray diffraction (XRD) studies. Field emission scanning microscopy (FE‐SEM) and energy‐dispersive X‐ray analysis (EDAX) have been used to study the surface morphology anda elemental composition. Fourier transform infrared spectroscopy (FT‐IR) was used to study the character and vibrational frequencies of bonds in the phosphor lattice. Room‐temperature PL was performed under 275 and 386 nm excitations, displaying a broad band in the blue region corresponding to the 3P1 → 1S0 transition of Bi3+ ions. The Commission Internationale de L'Eclairage coordinates and correlated color temperature values show that the as‐prepared phosphors emit in the blue vicinity. The decay curves under both excitation wavelengths show a single exponential behavior. Temperature‐dependent PL studies confirmed the high thermal stability of the phosphor. We want to endorse these phosphors as a blue‐emitting component in white light‐emitting diodes (w‐LEDs) and solid‐state lighting (SSL) applications.

Pressureless sintering of LRH nanoplates on amorphous alumina for near‐infrared GAP:Mn⁴⁺ transparent ceramic film

Transparent ceramics have become a research hotspot in the preparation of fluorescent materials in recent years, because of their excellent physical and chemical properties and high transparency. Gadolinium aluminate, as a stable matrix material, is often doped with various active ions to obtain luminescence with different colors. However, it is very difficult to fabricate gadolinium aluminate transparent ceramics by a traditional method, although they are the charming solid lighting materials. Here, we developed a pressureless sintering method to prepare GdAlO 3 :Mn (GAP:Mn) transparent ceramic films, which were prepared by spin coating layered rare-earth hydroxide (LRH) on amorphous alumina substrate and sintering at 1550 • C for 2 h. Through the interface reaction, the Al 2 O 3 reacted with Gd 2 O 3 to form mesophase Gd 4 Al 2 O 9 below 1550 • C. However, the final products are GdAlO 3 at 1550 • C. The GAP:Mn 4+ film exhibits a high transmittance of about 90%. Under UV excitation at 310 nm, the ceramic film outputs deep red and NIR emissions, which are both arising from the 2 E g -4 A 2g transition of Mn 4+ . Due to the electron traps arising from unequal valence substitution, the ceramic film exhibits a negative thermal quenching phenomenon. The ceramic film has a good luminescence thermal stability, because its emission intensity at 150 • C maintains over 72% that at room temperature. This work may pave a new way to fabricate transparent ceramics using LRHs.
