PbI2 Crystal

Description

Description PbI2 crystallizes into a CdI2 structure, in which I-anions are arranged in a hexagonal manner, and each Pb2+ cation is alternately layered with 6 I-anions, forming a typical octahedral structure. Repeated I-Pb-I trilayer stacking, in various ways and limited by van der Waals forces, provides a method to achieve monolayer and few-layer flakes by mechanical and chemical exfoliation due to the relatively low interlayer forces between them. Weakly adjacent layers.

Features And Benefits

Features And Benefits The PbI2 crystal product is perfectly layered with a direct band gap of 2.4 eV. Crystals arrive with perfect 0001 cleavage and are grown by floating zone technology for over 4 months to achieve perfect crystallization. PbI2 crystals are highly luminescent and have a guaranteed optical (photoluminescence) response.

Application

Application Energy storage, catalysis, analytical chemistry, mechanics, adsorption, biology, microelectronics, sensors, etc.
