Reference: AQA
Einstein's photons explained the photoelectric effect, which wave theory could not, and de Broglie then proposed matter waves, confirmed by electron diffraction.
The idea that both matter and electromagnetic radiation have wave and particle aspects, supported by electron diffraction and the photoelectric effect together.
