Black phosphorus crystals (CAS number 7723-14-0) can be used to produce single or few-layer phosphorene sheets via mechanical or liquid exfoliation.

Superior to transition metal dichalcogenides, the bandgap of black phosphorus can be tuned with the number of layers but remains direct regardless of the film thickness. The sensitivity of black phosphorus ultrathin structures to the incident light opens the door for ultra-fast photodetectors from ultra-violet to near infrared region of the electromagnetic spectrum.

Black Phosphorus Small Crystal

Black phosphorus small crystals, available by weight with a metal-like lustre look and in high purity, contain various sizes of black phosphorus crystals or lumps. Black phosphorus small crystals are good for physical and chemical exfoliation and intercalation. This makes black phosphorus an ideal candidate for high-capacity rechargeable batteries, tuneable electronic devices, and superconductors.

Black Phosphorus Bulk Crystal

Available as bulk crystal in different sizes and in high purity, black phosphorus crystal is ideal for mechanical exfoliation to obtain multilayer to single layer two dimensional nanosheets or nanoparticles in application of transistors, optoelectronics, sensors, batteries and catalysis.
