Structural, optical, thermal, mechanical, dielectric and laser damage threshold studies of a succinate salt of creatinine for nonlinear optical applications

• The chemical compositions of creatininium succinate (CS) were confirmed by NMR (1H and 13C) technique.
• Interestingly, the material exhibits large laser damage threshold up to 5.2 GW/cm2 and higher thermal stability of 245 °C.
• CS is a one of the low dielectric constant material with lesser defects.

In this work, the structural, optical, mechanical, dielectric, thermal and laser-induced damage threshold (LDT) studies of a promising organic NLO material creatininium succinate (CS) were reported. CS exhibits admirable properties such as good thermal stability (247 °C), low dielectric constant (εr=8.5) at higher frequencies and higher LDT up to 5.24 GW/cm2 (3.5 times greater than urea) which favor this material most suitable for advanced laser applications.
