Laser operated elasto-optical features of La2CaB10O19:Pr3+ polymer nanocomposites

We have discovered a principal role of the polymer matrices on the spectral dependences of piezooptical coefficients of La2CaB10O19:Pr3+ (LCBO:Pr) nanocomposites formed by polymethylmethacrylate (PMMA) and polycarbonate (PC) matrices. It was established that the optical treatment by the 10ns Nd:YAG...

Zusammenfassung:	We have discovered a principal role of the polymer matrices on the spectral dependences of piezooptical coefficients of La2CaB10O19:Pr3+ (LCBO:Pr) nanocomposites formed by polymethylmethacrylate (PMMA) and polycarbonate (PC) matrices. It was established that the optical treatment by the 10ns Nd:YAG laser can cause substantial changes of the dispersion of the piezooptical coefficients within the spectral wavelength 1400–1600nm. The optimal content of the LCBO:Pr with sizes ranging from 40 to 110nm corresponds to 4–6% in weighing units. Following the performed quantum chemical simulations, the observed changes are caused by different polarizabilities of the polymer matrices. ► Spectral dependences of piezooptical coefficients of La2CaB10O19:Pr3+ nanocomposites were studied. ► Substantial enhancement of the piezooptical dispersion was observed within the spectral range 1440–1520nm. ► The observed changes are caused by different polarizabilities of the polymer matrices.
