- Abstract
We synthesized 4,4'-dinitrophenyl 1,1'-adipamide (DNPA) and studied optical second harmonic generation (SHG) in this organic material using the Kurtz method. The experimental analysis of SHG was made for a range of particle size of DNPA. It was observed that DNPA is nearly three times more SHG active than urea. It was also found that the compound is non-phasematchable and did not show any optical degradation for about an year when kept in ambient atmosphere.
