Herein, the broadband orange phosphor Lu2CaMg2Si3O12:Ce3+ is prepared, and Lu3+ vacancy is created in the lattice to regulate the structure of this phosphor. This orange phosphor can be excited well by blue light and emit orange light ranging from 500 to 750 nm. By decreasing Lu3+ content in the lattice, the band gap of the matrix is widened. Besides, the emission of Ce3+ in this garnet structure is improved, and the emission of Lu1.84CaMg2Si3O12:Ce3+ reached the maximum of all the samples. The thermal stability of this orange phosphor is improved, and the emission of the phosphor Lu1.84CaMg2Si3O12:Ce3+ maintains 75.5% at 423 K compared to that at 298 K.

To ensure the long-term and stable operation of electronic devices in the internal environment, materials with conductivity, flexibility, biocompatibility, and other properties are in high demand. Hydrogels are polymers with three-dimensional network structures that not only have physical and chemical properties similar to those of biological tissues but can be also modulated by introducing functional groups to regulate the conductivity, adhesion, self-healing, and other functions. Therefore, hydrogel-based implantable bioelectronic devices are considered to be a candidate development direction in the future of the biomedical field. Here, this paper reviews the research progress in the molecular design and performance modulation of functionalized hydrogels based on four key properties of hydrogels: conductivity, self-healing, adhesion, and toughness. The latest progress in the use of functionalized hydrogels in implantable bioelectronic device applications is summarized below.

Herein, two co-administered drugs were determined by the second derivative synchronous spectrofluorimetric method in their pharmaceuticals and spiked human plasma; the first was celecoxib and the second was citalopram. Both celecoxib and citalopram had a native florescence, but their emission spectra showed a large overlap that complicated their determination by traditional fluorescence, this obstruction could be solved by measuring the synchronous fluorescence at Δλ = 70 nm, then deriving the second derivative allowing separation of celecoxib and citalopram with a zero-crossing point at 347 and 306 nm, respectively. In accordance with ICH instructions, method parameters were validated showing excellent sensitivity of the method, encompassing the concentration interval of 100.0–2000.0 ng/mL and 20.0–900.0 ng/mL for celecoxib and citalopram, respectively.

However, direct fluorescence detection of aspirin and telmisartan proved challenging because their native emission spectra at 406 and 375 nm overlapped. As a result, aspirin and telmisartan were measured utilizing synchronous fluorescence spectroscopy coupled with first-derivative spectroscopy, allowing for the entire resolution of their overlapping spectra and the measurement of aspirin and telmisartan at 416 and 349 nm, respectively.

Glycine, being a naturally occurring amino acid, serves as a sustainable, renewable, and low-emission alternative to conventional fuels, minimizing the environmental impact of the synthesis process. The research focuses on analyzing Judd–Ofelt (JO) parameters to explore the luminescent properties and optical performance of the nanophosphors, with a specific emphasis on their application in near-ultraviolet (UV) light-emitting diodes (LEDs). The combustion method employed produces nanophosphors with exceptional optical characteristics while reducing both energy consumption and harmful emissions. The study includes the synthesis process, structural characterization, and photoluminescence analysis of the LiGd₂₋ₓYₓ:Eu3+O₃ nanophosphors. By applying JO theory, the JO parameter analysis provides valuable insights into the luminescent behavior, enabling the optimization of optical properties for improved performance in near-UV LED applications. The findings highlight the importance of JO parameter analysis in refining the luminescent efficiency of these nanophosphors. Moreover, the use of the combustion technique promotes the development of innovative materials for next-generation optoelectronic devices.
