“…In recent years, UCNP materials have been rapidly developed in bioassays due to their special luminescent properties. The most common e cient UCNP systems use Yb 3+ as the sensitization ion, Er 3+ , Tm 3+ , Ho 3+ , Nd 3+, Pr 3+ , and other luminescent ions (Chien et al 2020;Yun et al 2021), and uoride (e.g. β-NaYF 4 ) as the doping substrate.…”

The accurate diagnosis and treatment of cancer cell lesions need a high standard of detection technology. Fluorescent probes to perform cancer biomarker detection have become a popular research issue. However, fluorescent probes still face enormous challenges of complex design and difficult detection. In this work, we propose a novel composite material UCNP@SiO2+QDs based on the combination of rare earth upconversion (UCNP) and perovskite quantum dots (QDs) and design a new fluorescent probe MB-UCNP@SiO2+QDs with molecular beacon (MB) as the carrier, that can be excited by near-infrared light, emitted in the visible wavelength, specifically identified and highly sensitive. Under the excitation of 980 nm near-infrared light, the UCNP and QDs in the composite produced the maximum efficiency of energy transfer through fluorescence resonance, and the multi-emission light of UCNP synergistically excited the re-emission of QDs, and the energy transfer efficiency is 70.6%. By changing the doping ratio of QDs halogen elements in UCNP@SiO2+QDs, it is possible to modulate the precise luminescence of UCNP@SiO2+QDs in the entire wavelength range of visible light at different positions. The novel fluorescent probe is obtained using UCNP@SiO2+QDs and Black Hole Quencher-1 (BHQ1) quenching groups linked to the two respective sides of MB, selecting as the target of detection the myeloma cancer biomarker miRNA-155, a difficult diagnostic and complex developmental type, and have achieved specific recognition and low concentration of miRNA-155 and a detection limit of 73.5 pM. This fluorescent probe design can provide new ideas for the early diagnosis and treatment of cancer, tumors, and cardiovascular diseases.

“…Due to the abundant energy levels and the underfilled 4 f electronic layer structure of rare earth (RE) elements, various electronic energy level transitions have occurred. In recent years, rare earth materials show unique advantages over other non‐rare earth materials due to their varied transition characteristics [1–3] . Many studies have shown that trivalent RE ions doped nanomaterials have huge application prospects and valuable market value in many fields, such as optics, electricity, magnetism, and biomedicine [4,5] .…”

Emission Brightness and Concentration Quenching Threshold of GdVO₄ : Eu³⁺ Nanophosphors Co‐Doped with Alkali Metal Ions

GdVO4 : Eu3+ nanophosphors co‐doped with alkali metal ions (Li+, Na+, K+) of various concentrations were fabricated by an efficient hydrothermal method. The microstructure and luminescent emission properties were tested systematically. The results demonstrated that the co‐doping of M+ led to lattice distortion, which is closely related to dopants’ ionic radii and concentrations. The lattice distortion further resulted in a fluctuation of luminescent brightness. The optimal luminescent properties of GdVO4 : Eu3+ co‐doped with Li+(10 atom‐% (at. %)), Na+(8 at. %), K+(6 at. %) were achieved respectively. Among them, the GdVO4 : Eu3+ co‐doped with Li+ of 10 at % possessed the highest emission intensity. Moreover, the alkali metal ions co‐doping also gave rise to the elevation of the concentration quenching threshold of Eu3+, which further enhanced the luminescent performance.
