摘要

Potassium dihydrogen phosphate (KDP) crystal has established itself as a very desirable material for optical, piezoelectric, and laser applications. This article discusses high-quality KDP single crystals that were produced with and without temperature-induced conditions utilizing the slow evaporation solution method. After 20 days of growth, the size of the developed KDP single crystals was measured at 13 × 16 × 3 mm3 for without temperature (WOT) and 40 × 24 × 6 mm3 for with temperature (WT). The produced crystal was used for powder X-ray diffraction (PXRD), and the increasing intensity of the sharp peak confirms the material’s high crystallinity and phase purity. The functional groups were verified using Fourier transform infrared (FTIR) spectroscopy. According to UV–Visible research, the greatest transmittance of KDP-grown crystals is often lower (about 96%) when heat is applied and greater (about 98%) when no heat is applied. Differential scanning calorimetry (DSC) shows where the breakdown takes place at 215.27 °C (WT) and 231.13 °C (WOT), respectively. The melting temperature is shown by the endothermic peak in the derivative thermogravimetry (DTG) plot, which was found at 234.6 °C (WOT) and 229.4 °C (WT) in thermogravimetric analysis (TGA)/DTG. According to photoacoustic spectroscopy (PAS), KDP WT crystal’s thermal diffusivity value is marginally greater than KDP WOT crystals. Using photoluminescence (PL) analysis, the KDP WOT and WT crystals showed a wide luminescence emission peak at 396 nm. The thermal parameters of a sample are determined by the analysis of PAS, and the obtained outcome makes the crystal suitable for optical and laser applications. The grown KDP crystal’s TGA/DTG analyses yield positive results and are recommended for use in electro-optical device applications.
