This dataset comprises original images and videos collected during experiments on the nucleation and crystal growth from supersaturated aqueous solutions of sodium bromide.
Different methods were used to induce nucleation: mechanical shock-induced nucleation, nucleation by ultrasound (sonocrystallization), non-photochemical laser-induced nucleation (NPLIN) and laser-trapping nucleation. The most stable crystal form at room temperature is known to be sodium bromide dihydrate (DH) and this form was favoured (> 95%) through spontaneous nucleation or mechanical shock. Sonocrystallization favoured DH crystals (74%). Remarkably both laser-induced nucleation methods showed a strong preference (> 90%) for anhydrous (AH) crystals.
