The process of finding or distinguishing whether or not the specimen to be examined is an explosive entails the use of photoluminescence copolymers metal-metal bond. In this case it can be Si-Si or Ge-Ge bond. It is also used by putting a thin film of the copolymer in an analyte (thus the object to be analyzed) for instance as the use of trinitrotoluene (TNT) or picric acid. This process involves finding out the slaking of the photoluminescence of the polymetalloles using toluene solution which examines the wavelengths produced from the analyte. This helps in distinguishing whether the specimen is an explosive or not.
The process of detection is based on the transfer of electrons from their excited state in the metallole copolymer up to the ground state or the lowest energy level of the analyte that is not occupied by any electrons. The electrons can be excited by using electrical methods or by optical ways. In the case of the optical methods, a source of light that has larger wavelengths may be required and this can be done using a mercury lamp or a diode that produces ultraviolet rays.
