TGPLS MatriX-1

Ultrafast Spectroscopy超快光谱仪

Overview概述

TGPLS MatriX-1 [Time-Resolved Photoluminescence spectroscopy] is the first commercially available broadband 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 to tens 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. TGPLS MatriX-1 breaks 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. The TGPLS MatriX-1 instrument 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, TGPLS MatriX-1 is the benchmark next generation time resolved fluorimeter.

TGPLS MatriX-1 [时间分辨光致发光光谱仪]，是第一台商用的设计用于飞秒放大激光系统的宽带荧光光谱仪。时间分辨荧光(或光致发光)光谱广泛用于揭示发射材料中的电子激发态动力学，从半导体到纳米材料、染料和蛋白质。其他时间分辨荧光光谱仪可分为两类：宽带光谱分辨率，时间分辨率限制在几十皮秒或更长；超快时间分辨率，仅限于单波长扫描。这两种方法都不能充分捕捉到与许多关键光物理过程相关的超快光谱演化。TGPLS MatriX-1 打破了这一局限，它具有捕捉飞秒级宽带荧光光谱的独特能力，具有高信号质量、低背景噪声和高速数据采集。TGPLS MatriX-1 是基于由新西兰惠灵顿维多利亚大学（Victoria University of Wellington, New Zealand）的超快光谱研究人员开发的瞬态光栅专利技术。结合瞬态光栅的固有优势，以及光谱仪开发的软硬件用户界面，TGPLS MatriX-1 是下一代时间分辨荧光计的基准。
