The material inside a LED is typically a semiconductor such as gallium arsenide (GaAs), gallium phosphide (GaP), or gallium nitride (GaN). These materials are used because they can emit light efficiently when an electric current passes through them. The semiconductor is usually encased in a plastic lens, which helps to focus and direct the light.
