Integrated Metallo‐Dielectric 3D Hotspots From High Refractive Index Nanodiamond‐Plasmonic Gold Cryosoret Nano‐Assemblies for Photonic Crystal Enhanced Fluorescence

open access: yesAdvanced Functional Materials, Volume 36, Issue 5, 15 January 2026.
This work presents a novel sensing platform using metallo‐dielectric cryosoret nano‐assemblies and lossless photonic crystals to overcome limitations of conventional plasmonic biosensors. The hybrid system enhances both electric and magnetic field interactions, enabling amplified fluorescence, ultralow detection limits, and prism‐free, objective‐free ...

Analysis of 5G NR coverage capability at 2.6 GHz

open access: yesDianxin kexue, 2019
The current research on 5G new air interface is mainly concentrated in the middle and high frequency bands.The low frequency band re-cultivation used by 4G is of great significance for 5G-scale contiguous networking,but there are few studies.On the basis

Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

Remote Radio Frequency Sensing Based on 5G New Radio Positioning Reference Signals

open access: yesSensors
In this paper, the idea of a radar based on orthogonal frequency division multiplexing (OFDM) is applied to 5G NR Positioning Reference Signals (PRS). This study demonstrates how the estimation of the communication channel using the PRS can be applied ...

Anion Effect on the Thermometric Properties of Near‐Infrared Emitting Mn5+‐Activated Sr5(PO4)3X (X = F, Cl, Br) Apatite Phosphors

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Mn5+‐activated Sr5(PO4)3X (X = F, Cl, Br) apatite phosphors exhibit tunable near‐infrared thermometric behavior across cryogenic to high temperatures. The correlation between local [PO4]3– geometry and optical properties enables the prediction of suitable hosts directly from structural information.
