TGPLS MatriX-1

Ultrafast Spectroscopy超快光譜儀

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 [時(shí)間分辨光致發(fā)光光譜儀]，是**臺(tái)商用的設(shè)計(jì)用于飛秒放大激光系統(tǒng)的寬帶熒光光譜儀。時(shí)間分辨熒光(或光致發(fā)光)光譜廣泛用于揭示發(fā)射材料中的電子激發(fā)態(tài)動(dòng)力學(xué)，從半導(dǎo)體到納米材料、染料和蛋白質(zhì)。其他時(shí)間分辨熒光光譜儀可分為兩類：寬帶光譜分辨率，時(shí)間分辨率限制在幾十皮秒或更長(zhǎng)；超快時(shí)間分辨率，僅限于單波長(zhǎng)掃描。這兩種方法都不能充分捕捉到與許多關(guān)鍵光物理過(guò)程相關(guān)的超快光譜演化。TGPLS MatriX-1 打破了這一局限，它具有捕捉飛秒級(jí)寬帶熒光光譜的獨(dú)特能力，具有高信號(hào)質(zhì)量、低背景噪聲和高速數(shù)據(jù)采集。TGPLS MatriX-1 是基于由新西蘭惠靈頓維多利亞大學(xué)（Victoria University of Wellington， New Zealand）的超快光譜研究人員開(kāi)發(fā)的瞬態(tài)光柵**技術(shù)。結(jié)合瞬態(tài)光柵的固有優(yōu)勢(shì)，以及光譜儀開(kāi)發(fā)的軟硬件用戶界面，TGPLS MatriX-1 是下一代時(shí)間分辨熒光計(jì)的基準(zhǔn)。
