Concentration-dependent enhancement of nonlinear optical properties in Ge-Te-Bi nano colloidal solutions
ABSTRACT We have investigated the preparation and nonlinear optical characterization of Ge20Te75Bi5 (GTB) nano colloidal solutions using the z-scan technique for three different concentrations. The transmission spectra of GTB nano colloid films have been investigated. FTIR spectra have been measured to confirm the presence of amines in nano colloidal solutions. Z-scan traces at 78 × 1012 W/cm2 laser intensity were used to study the nonlinearity of the samples. The nonlinear absorption coefficient increases with an increase in the concentration of nano colloids. The reported high nonlinear response is useful for optical limiting applications. The optical limiting behavior is also studied against different concentrations.
期刊介绍:
Phase Transitions is the only journal devoted exclusively to this important subject. It provides a focus for papers on most aspects of phase transitions in condensed matter. Although emphasis is placed primarily on experimental work, theoretical papers are welcome if they have some bearing on experimental results. The areas of interest include:
-structural phase transitions (ferroelectric, ferroelastic, multiferroic, order-disorder, Jahn-Teller, etc.) under a range of external parameters (temperature, pressure, strain, electric/magnetic fields, etc.)
-geophysical phase transitions
-metal-insulator phase transitions
-superconducting and superfluid transitions
-magnetic phase transitions
-critical phenomena and physical properties at phase transitions
-liquid crystals
-technological applications of phase transitions
-quantum phase transitions
Phase Transitions publishes both research papers and invited articles devoted to special topics. Major review papers are particularly welcome. A further emphasis of the journal is the publication of a selected number of small workshops, which are at the forefront of their field.
