2026-06-08 Dataset of impurity concentrations and third-harmonic absorption coefficients in DKDP crystals doi:10.57760/sciencedb.38555 en This dataset contains the raw data used in the paper "Effect of Trace Metal Impurities and Their Segregation Mechanisms on the Third-Harmonic Absorption of DKDP Crystals" for the "correlation analysis between impurity content and absorption coefficients." The dataset includes the third-harmonic (351 nm) absorption coefficients for 13 DKDP crystal samples, as well as the concentrations of 11 impurity elements (in ppm); the sample numbers are identical to those in Dataset 1. The impurity elements include: Al, Ba, Co, Cr, Cu, Fe, Sb, Sr, Ti, Y, and Zn. These data correspond one-to-one with the absorption coefficients in Dataset 1 and can serve as the foundational data for the correlation analysis between the two datasets.The data file is in CSV format and contains the following columns:Sample ID (Sample Number)Absorption Coefficient (cm⁻¹) (terahertz absorption coefficient)Al (ppm), Ba (ppm), Co (ppm), Cr (ppm), Cu (ppm), Fe (ppm), Sb (ppm), Sr (ppm), Ti (ppm), Y (ppm), Zn (ppm)This dataset can be used directly to reproduce the statistical analysis process described in the paper regarding the correlation between various impurity elements and absorption coefficients.Data Note: The concentration values provided in this dataset are the actual internal concentrations of the samples after conversion. The conversion is based on the dilution factor during the sample digestion process; the original ICP-MS dilution solution measurements are not included in this dataset. Data points deviating from the normal range were excluded from the statistical analysis, and the corresponding cells are marked with “/”. The Y content in several samples was close to the detection limit (0.0004 ppm), resulting in an abnormal data distribution; therefore, it was excluded from the key impurity analysis in the paper. The original data is retained in this dataset for users to handle at their discretion.
