TGPLSMatriX-1

Ultrafast Spectroscopy超快光谱�?/span>

Overview概述

TGPLSMatriX-1[Time-Resolved Photoluminescence spectroscopy] is the first commercially availablebroadband fluorescence spectrometer designed for femtosecond amplifier laser systems. Time-resolved fluorescence (or photoluminescenc e) spectroscopy is widely used to reveal electronic excited state dynamics in emissive materials ranging from semiconductors� to nanomaterials� dyes� and proteins. Other time resolved fluorescence spectrometers fall in two categories; broadband spectral resolution with time resolution limited totens of picoseconds or longer; or ultrafast time resolution limited to single wavelength scans. Neither of these approaches adequately captures ultrafast spectral evolution associated with a host of critical photophysical processes.TGPLSMatriX-1breaks this tradeoff with the unique ability to capture broadband fluorescence spectra on femtosecond timescales� with high signal quality� low background noise� and rapid data acquisition. TheTGPLSMatriX-1instrument is based on patented transient grating gate technology developed by ultrafast spectroscopy researchers at Victoria University of Wellington� New Zealand. Combining the intrinsic advantages of transient grating gate� and hardware and software user interfaces developed by spectroscopists�TGPLSMatriX-1is the benchmark next generation time resolved fluorimeter.
