Lead Selenide Quantum Dot	PBSE-QD

American Elements is a manufacturer and supplier specializing in producing Lead Selenide (PbSe) Quantum Dots. PbSe Quantum Dots are finding important application in solar energy due to their extremely wide band gap in which it absorbs light. American Elements manufactures quantum dots from several semiconductor materials, including Cadmium Telluride (CdTe), Cadmium Selenide/Zinc Sulfide (CdSe/ZnS), Lead Selenide (PbSe) and Zinc Cadmium Selenide/Zinc Sulfide (ZnCdSe/ZnS) nanoparticles with well-defined peak emission frequencies.

Lead is a Block P, Group 14, Period 6 element. The number of electrons in each of Lead's shells is 2, 8, 18, 32, 18, 4 and its electronic configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p². In its elemental form lead's CAS number is 7439-92-1. The lead atom has a radius of 175.pm and its Van der Waals radius is 202.pm. Lead and its compounds are poisonous. Lead is a bluish-white metal of bright luster, naturally occurring as a mixture of four stable isotopes: 204Pb (1.48%), 206Pb (23.6%), 207Pb (22.6%), and 208Pb (52.3%). It is highly resistant to corrosion and can be used to contain corrosive liquids such as sulfuric acid. Great quantities of lead, both as the dioxide and the metal, are used in batteries, cable covering, plumbing, and ammunition. Alloys include solder, type metal, and various antifriction metals and compounds. Lead is extremely effective at absorbing sound and vibration. It is also used as radiation shielding for X-ray equipment and nuclear reactors. Oxides of Lead are used in producing fine "crystal glass" and "flint glass" of a high index of refraction for achromatic lenses. Lead ceramics and crystalline material have a wide range of industrial and optical applications, including infrared detection and imaging. Lead-based semiconductors, such as lead telluride, lead selenide and lead antimonide are finding application in photovoltaic (solar energy) cells and infra red detectors. Lead is obtained mainly from galena (PbS) by a roasting process. Anglesite, cerussite, and minim are other common lead minerals. Lead was first discovered by Early Man. The origin of the name Lithium comes from the Greek word protos meaning "first". See Lead research below.
