Silver Sulfide Quantum Dots (Ag ₂ S QDs) are a type of semiconductor nanocrystals composed of silver (Ag) and sulfur (S) elements (typically<10 nm in size), with quantum confinement effects and unique physicochemical properties.

Basic characteristics

1.Chemical composition: The chemical formula is Ag ₂ S, with silver having a+1 valence and sulfur having a -2 valence. It belongs to binary semiconductor materials.

2.Crystal structure: The common phase is the monoclinic system of β - Ag ₂ S (stable at room temperature), which can transform into the cubic phase of α - Ag ₂ S at high temperatures.

Band structure:

1.The bandgap of bulk Ag ₂ S is approximately 0.9-1.1 eV (near-infrared band), but quantum dots can adjust the bandgap to 0.7-1.3 eV due to size effects.

2.Manifested as a narrow bandgap semiconductor, suitable for near-infrared (NIR) optoelectronic devices.

Specification of Silver sulfide quantum dots liquid:

Product Features

Application of Silver sulfide quantum dots liquid:

1. Biomedical:

Tumor imaging: NIR fluorescence labeling of cancer cells.

Treatment: Photothermal conversion (absorbing light energy to generate heat and kill tumors) or photodynamic therapy (producing reactive oxygen species).

Drug delivery: Loading drugs onto the surface after modification to achieve targeted release.

2. Optoelectronic devices:

Near infrared photodetectors, solar cells (as absorbing layers or electron transport layers).

Catalysis: Photocatalytic degradation of pollutants or hydrogen production.
