I am sorry I forgot a term in emission spectroscopy, please help

When you do emission spectroscopy, you will see a sharp emission whose wavelength being double of the excitation wavelength, what is it called? ( I remember it is something secondary scattering)

Why does this happen?

2nd order scattering/diffraction. It's caused by the diffraction grating present in your monochrometer.
