In the advance technology of nano the studies shows that this is a type of or part of nano scale objects. Their dimensions can vary from 1 to 100 nm. They can be produced by metals or semiconductor materials. Research shows that they are produced by direct chemical materials. It is also found that if an ion or molecule is attached to a metal atom by the bonding of coordination then it can be produced with different strength and rates.

These rods are normally based on semi conduct materials and have been investigated as source of energy for light and other devices. Nano rods can be found as structure with single dimension which gives the direction for transportation of electricity and therefore is used to control over band gap. It may result vary in different cases of radius, size and shapes.

There are many types of rods but due to the multiple properties of nanowires, nanorods and nanobelts. Zinc oxide has proven to be very effective. It is like most effective in the case of band gap also it has proven best, as it has good binding even at room temperature. They are very effective in the field of electronic devices and therefore the studies made on the application of such like on nano laser, photo detector, solar cells etc.

Worldwide, multiple type of these rods are grown by many groups of researchers. The structure of nano surface has been found as quite typical to find out the electronic and electrical property of nano rods. Therefore it has the capabilities of achieving high sensitive response in much faster way if compared to bulk order. Many efforts have been made up till now to improve the behavior of photo detection and photo response.

By using proper method of structural improvement and phototronic effect or by making hetero structure with appropriate organic and inorganic, multiple groups have worked on this issue to achieve the goal. These are semi conductor compounds whose ionic nature is found between ionic semiconductor and covalent. It can be found in crystal structure in the form of wurtzite, zinc blende, and rocksalt. Here it must be noted that only wurtzite are found as a stable in the sense of thermodynamical.

There are many methods, such as mechano synthesis method, Vapor–phase synthesis method and so on.

This mechano synthesis method is generally used for synthesizing the quantom dots or nano crystals in different sizes. By this technique they are synthesized by many groups. For the proper growth proper surface is required, so that it can grow in one direction. So for making it grow in just one direction this is a very tactful way to implement. The importance of these methods is it can be grown in the temperature of room only and in much faster way, if it is compared to other chemical methods.

The other method is vapor phase synthesis method which is quite affective to the larger extent and area if compared with the other ones. It is used for one dimension nano structure. It is found to be more successful in terms of generating or producing large amount of nano wires.
