A series of LiBaY(MoO) phosphors, co-doped with Sm and Eu, were successfully fabricated through a high-temperature solid-phase synthesis approach. An exhaustive analysis was undertaken, encompassing the purity of the powder phase, the crystalline structure, morphological characteristics, elemental distribution, luminescent behavior, thermal robustness, and electroluminescent properties. The phosphor has high activation energy (0.40 eV) and good thermal stability. The light emission spectra of light-emitting diode (LED) devices fabricated using commercially available 400 nm LED chips and LiBaY(MoO):0.12Sm/0.06Eu were highly overlapped with the absorption bands of P, P phytochromes, and chlorophylls a and b. These results demonstrate the significant potential of Sm/Eu co-doped LiBaY(MoO) phosphors for plant growing applications.

Single-component white-light-emitters ensure color stability while reducing device complexity, and are ideal candidates for white light-emitting diodes (WLEDs). However, the realization of single-component white-light emission with high efficiency and stability is still a challenge. Herein, a supramolecular cation strategy was used to synthesize the organic-inorganic hybrid copper(I) halide [(AMTA)(18C6)]CuI (1), with AMTA = 1-adamantanamine and 18C6 = 18-crown-6.

Here, Ln-Li co-doped YO@ZnO core-shell heterostructures were synthesized by three different techniques - intermediate layer conversion method, a hydrothermal method, and an interlayer mediated hydrothermal method. The synthesis procedure is optimized based on the thickness and compactness of the developed shell. The growth kinetics and synthesis mechanism of each adopted method have been explained in detail using XRD, FESEM, TEM, SAED, and EDX characterization techniques.

The synergistic effect of various ions with optical properties is an important method to regulate the Er ion upconversion luminescence process. However, the energy processes between them are complicated and difficult to separate, and it is challenging to clarify the results of each process when multiple ions are co-doped. Herein, a series of NaYF:Er were synthesized by the low-temperature combustion method, and the luminescence color of Er ions was modulated by doping Yb ions and Tm ions.

Liquid is the most flexible state of condensed matter and shows promise as a functional soft material. However, these same characteristics make it challenging to achieve efficient room-temperature phosphorescence (RTP) from metal-free organic molecular liquids. Herein, we report efficient RTP from liquefied thienyl diketones bearing one or two dimethyloctylsilyl (DMOS) substituents.

Rare-earth ions (REIs), especially trivalent lanthanides (Ln ), are central to photonic technologies due to sharp intra-4f transitions, long lifetimes, and host-insensitive emission. However, modeling REIs remains challenging due to localized 4f orbitals, strong electron correlation, and multiplet structures. This review summarizes atomistic modeling strategies combining quantum chemistry and machine learning (ML).
