Article Abstract
Nanoparticles and nanoribbons of SbPO4 and lanthanide ions (Eu3+, Ce3+ and Tb3+) doped SbPO4 were prepared at a low temperature of 120 degrees C by co-precipitation method in solvents like ethylene glycol and glycerol. By varying the relative ratios of the two solvents, average crystallite size of SbPO4 has been varied over a range of 12 to 46 nm. Based on steady state luminescence studies, existence of energy transfer between host SbPO4 and lanthanide ions has been confirmed. Co-doping SbPO4:Tb3+ nanoparticles/nanoribbons with Ce3+, resulted in improved luminescence due to energy transfer from Ce3+ to Tb3+ ions. Further, these nanomaterials can be incorporated in sol-gel derived silica glass without any deterioration of their luminescence properties. Present study offers a viable method for preparing composite luminescent materials based on nanoparticles/ nanoribbons and glasses.

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.

Electrochemiluminescence (ECL) imaging through closed bipolar nanoelectrode arrays (BPnEAs) has emerged as a promising method for in situ label-free wide-field electrochemical imaging. In this study, a cathodic ECL system based on [Ru(bpz)]/SO is combined with the BPnEAs fabricated on silicon nitride membrane windows through focused ion beam nanofabrication, enabling effective bipolar imaging of heterogeneous anodic electrocatalytic reactions. The shape, distribution, size, and material composition of individual electrodes within the array can be precisely controlled.

Background: Of the mycotoxins, aflatoxin is the most significant. The detection of aflatoxin B1 (AFB1) is crucial for ensuring food safety, as this highly carcinogenic toxin readily contaminates crops such as grains and nuts, and timely detection can effectively prevent associated health risks. The selection of luminophores is of paramount importance in the detection of ECL (electrochemiluminescence).
