Abstract: A method of determining crystallinity may include acquiring a Raman spectrum of each of samples that are crystallized, determining a first sample that exhibits a first Raman spectrum having a first Raman intensity that is largest among the Raman spectra, as an optimal sample, and determining a second sample that exhibits a second Raman spectrum having a second Raman intensity that is within a range from the first Raman intensity based on the first Raman intensity, as a first normal sample.
