Spectral and dynamical study of nonlinear luminescence from silicon nanocrystals excited by ultrashort pulses

implantation into a silica matrix. We concentrate on the luminescence properties that make it possible to distinguish several luminescence bands within a broad luminescence spectrum. In time-integrated luminescence

Temperature dependent luminescence characteristics of KBe2BO3F2 and RbBe2BO3F2./sub

This paper reports on a study of the luminescence characteristics of KBe2BO3F2 KBBF) and RbBe2BO3F2(RBBF) crystals in UV/visible spectral range. The KBBF crystals are very popular for their nonlinear optical properties, however they...

Si nanocrystals in a distributed feedback laser cavity

We investigate an optically induced distributed-feedback cavity, containing a densely packed luminescent silicon nanocrystal layer in a SiO2 based matrix as active medium a nonlinear increase in the spectrally resolved emission inte...

Electron-Withdrawing Substituted Quinazoline Push-Pull Chromophores: Synthesis, Electrochemical, Photophysical and Second-Order Nonlinear Optical Properties

-trifluorophenyl)quinazoline derivatives are highly luminescent in chloroform solution, 4-cyanoquinazolines are poorly emissive. Interestingly all compounds are luminescent in the solid state with the emission ranging from blue to r...

Temperature effects in the anomalous decay of luminescence: nonlinear breathers and the impact of noise

The decay anomaly in doped alkali halides has been shown to result from the formation of a discrete breather. In the present work we introduce noise into the system and study the frequency evolution in order to investigate breather decay in a noisy e...

Synthesis, characterization and non-linear optical response of organophilic carbon dots

For the first time ever we report the nonlinear optical (NLO) properties show significant NLO response. Specifically, the C-dots show negative nonlinear absorption coefficient and negative nonlinear refraction. Using suspen...
