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.

Nematic Liquid Crystals (LCs), noted for their simple molecular alignment and broad use in optoelectronics, remain unmodified for over a century. However, in 2017, a unique polar phase, the ferroelectric nematic (N), is confirmed. Subsequently, in 2024, the revolutionary spontaneous mirror symmetry breaking of ferroelectric twist-bend nematic chiral structures (N phase) is demonstrated.

Transparent meltable glasses are keenly desired for making color-conversion layer of Mini-LEDs. In this work, transparent luminescent organic glasses were prepared using a new matrix of heptyltriphenylphosphonium bromide (CHBrP, HTPBr). Through doping of a blue dye (9,10-diphenylanthracene, DPA), the resulting glass exhibited a high transparency (92%) and a blue emission at 436 nm.

Recent quest for emulating lifelike smart materials for developing functional outcomes has been spurred by the unparalleled spatiotemporal control of natural systems. However, it is still highly challenging to replicate the progressive time-dependent programmable features of biological systems, such as adaptive broad-spectrum luminescence accompanying functions. Here in, a chemically-fueled transient hydrogel is created based on an aggregation-induced emission-active peptide conjugate (NI-VD).

Beyond single-photon emission, generating correlated -photon bundles, e.g., a photon pair, is essential for various quantum technologies including quantum teleportation and metrology.
