Radioactive radiation is a high-energy process that emits high-energy particles and light waves from atoms. This process can alter the atomic structure of materials such as graphene oxide (GO), thus changing their electrical conductivity properties. GO possesses unique features such as a high surface area and high connectivity, which allows for the generation of electric current through the transportation of electrons and holes. Radioactive radiation, by altering the atomic structure, can change the energy levels, conduction band, and even the semiconductor properties of a diode. These changes can affect the light emission spectrum, color, and even the optoelectronic properties of the diode. Consequently, radioactive radiation can be used as a new method to control the light emission properties, color, and even electrical conductivity of GO diodes. This creates new opportunities for the design and application of next-generation optoelectronic devices.
