The Purchase of a Single Photon Counting Fluorimeter with Lifetime Capability

在化学研究仪器和设施(CRIF)计划的这一奖项下，普渡大学化学系将获得一台具有寿命能力的单光子计数荧光仪。这台设备将加强研究，探索铜(I)络合物在溶液中的激发态反应性；铜(I)-和AMP；Ru(II)-基给体-受体络合物中的光诱导分子内电子转移；以及气体小分子对酸性沸石中溶剂变色有机阳离子及其电荷转移络合物吸收和发射的影响。荧光光谱仪计算紫外(UV)和可见光区域的光子。当材料样品被给定频率或能量的紫外光照射时，反射光由原始紫外光组成，但也可能包含光谱可见区域中较低频率或能量的光。荧光计是一种非常灵敏的仪器，用于检测荧光信号。

With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Purdue University will acquire a Single Photon Counting Fluorimeter with Lifetime Capability. This equipment will enhance research which explores the excited state reactivity of Cu(I) complexes in solution; photo-induced intramolecular electron transfer in Cu(I)- & Ru(II)-based donor-acceptor complexes; and the effect of small gas molecules on the absorption and emission of solvatochromic organic cations and their charge-transfer complexes within acidic zeolites.The fluorescence spectrometer counts photons of light in the ultraviolet (UV) and visible regions. When a sample of material is illuminated by UV light at a given frequency or energy, the reflected light consists of the original UV light, but also may contain light in the visible region of the spectrum, at a lower frequency or energy. The fluorimeter is a very sensitive instrument used to detect the fluorescence signal.
