In the present work, ZnGa2O4 was incorporated with g-C3N4 nanosheets to synthesize ZnGa2O4/g-C3N4 nanocomposites through the hydrothermal method. The morphologies of nanocomposites were characterized by TEM, XRD, and spectral and electrochemical methods, respectively. The nanocomposites exhibited greatly enhanced fluorescence with the maximum emission peak red-shifted from 380 nm to 450 nm.

Electrogenerated chemiluminescence (ECL) of Ru(bpy) was studied at a MoS nanosheets modified glassy carbon electrode (MoSNS/GCE) in neutral condition. Electrochemical results revealed that MoS nanosheets could significantly catalyze the electrochemical oxidation of Ru(bpy), as a result, strong anodic ECL was obtained. Several impact factors, such as the modified amount of MoS nanosheets suspension, the pH value, and the concentration of Ru(bpy), were investigated to obtain the optimal experimental condition.

In this work, the electrochemiluminescence (ECL) behavior of a luminol-H2O2 system was studied on a black phosphorus nanosheet (BPN) modified electrode. A quenching effect of BPNs on luminol ECL was achieved based on ECL resonance energy transfer (ECL-RET) with excited state luminol as the energy donor and BPNs as the energy acceptor. Protamine could bind on the surface of BPNs through electrostatic interactions, which can cut off the energy transfer route between luminol and BPNs to restore the ECL signal.

Black phosphorus nanosheets (BPNS) were synthesized from BP crystals through liquid exfoliation coupled with ultrasonic methods under aqueous conditions. The morphology of the synthesized BPNS was characterized by TEM, XPS, AFM, Raman spectroscopy, UV-vis absorption and fluorescence spectroscopy, respectively. The obtained BPNS exhibited a multilayer structure and the lateral length was around 300 nm, and could emit fluorescence at 380 nm.

Black phosphorus quantum dots (BPQDs) with an average size of 8.2 nm were synthesized through a liquid exfoliation method. The surface morphology and the thickness of the BPQDs were identified by high-resolution transmission microscopy (HRTEM), atomic force microscopy (AFM), and Raman spectroscopy.
