 Description:
It is a general and well-known fact that Nano-materials are behaving differently from their bulk material. Size and shape control many of the physical properties (viz., melting point, magnetism, Specific heat, conductivity, bandgap, etc.), luminescence, optical, chemical, and catalytic properties of nanomaterials. The present research has been done, based on these facts and the New Nano-sized Pb metallic semiconductor has been innovated. The photoluminescence study of lead Nanopowder confirms the emission of photons. It suggests the presence of a bandgap in the material and its semiconducting properties.
 A semiconductor is a material which has electrical conductivity between that of a conductor such As copper and an insulator such as glass. The conductivity of a semiconductor increases with increasing temperature, behavior opposite to that of a metal. The most common semiconducting materials are crystalline solids. They are defined by their unique electric conductive behavior. They can pass current more easily in one direction than the other. Their conductive properties can be modified by controlled addition of impurities or by the application of electrical fields or Light. Metal conductivity decreases with temperature increase because thermal vibrations of Crystal lattice disrupt the free movement of electrons. Bulk lead metal is a good conductor but lead Nanoparticles behaving differently and showing some resistance in four probe test. Semiconductor resistivity is indirectly proportional to temperature. It increases with decreasing temperature and vice versa. 4 eV bandgap value is the rough dividing line and it determines whether a material is a semiconductor (less than 4 eV) or an insulator (more than 4 eV).
 Semi-Conductor Mechanism in Pb Nanoparticles
 Metallic nanoparticles possess unique optical, electronic, chemical, and magnetic properties that are strikingly different from that of the individual atoms as well as their bulk counterparts. The optical properties of nanoparticles are closely related to size-induced changes in the electronic structure and directly reflect the size-dependent energy structure of the particles. Spectroscopic methods probe the energy differences between the two states for allowed transitions. The size effect on the optical absorption spectra of metallic nanocrystals is probably best known for the noble metal nanoparticles. Nanomaterials exhibit interesting size-dependent electrical, optical and magnetic properties which are different from both atomic and bulk- level. At the nanoscale, because of quantum mechanics effects, they behave differently as compared to bulk materials. Indeed the emerging properties are due to the quantity variation in a number of atoms i.e. in nanoparticles, a number of atoms are less than their bulk matter where millions of atoms together. Also, because of compactness, there are split into energy levels. So, even in magnetic applications, there is more control. For example, as the size decreases, the bandgap of material increases.

Al2S3 Description :
Sulfides
Inorganic sulfides are ionic compounds containing the sulfide ion S2−. Sulfide compounds can be used in a wide variety of applications including solid-state electrolytes, cathode materials in lithium-ion and thermal batteries, semi-conductors in thermoelectric devices, as part of phosphor compositions, as photovoltaic materials, as pigments, and a variety of other applications. Nanochemazone is a world-leading manufacturer in the production of sulfide compounds with one of the most comprehensive selections of sulfides and extensive sulfide-manufacturing expertise. Most sulfides are manufactured as powders in large batch quantities but certain commercial sulfides are available in large metric-ton quantities. Additionally, Nanochemazone can custom synthesis sulfides that may not be listed in our catalog and can modify sulfides to customer's specifications including producing mixed sulfides, non-stoichiometric compositions, or special purities and particle sizes.
Aluminum Sulfide Applications:
Aluminum sulfide, also known as aluminium sulphide, is a compound of aluminum and sulfur with the formula Al2S3. A colorless or gray solid with an exceptional sensitivity to moisture, aluminum sulfide is not to be confused with the more widely used aluminum sulfate, Al2(SO4)3. Exposed to the atmosphere or other sources of moisture, aluminum sulfide will hydrolize into aluminum hydroxides and hydrogen sulfide gas. This makes careful storage and handling a priority.
Many of the most interesting applications of aluminum sulfide remain in the early research phases, with many researchers eager to explore its value in aluminum-sulfur energy story.Â
- Energy storage. A subject of research in the production of aluminum-sulfur batteries, a potentially superior alternative to lithium batteries.
- Like several similar metal sulfides, aluminum sulfide may be of value for its photovoltaic properties at smaller scales.
- Useful for its reactivity in producing several commercially or academically valuable compounds.
- Aluminum source. Moderately water and acid soluble source for aluminum.
