该系统由 Quantaurus-QY Plus (C13534-11、-12) 组成,并添加了一个补充单元:NIR PL 测量单元。
由于传感器的灵敏度,用于测量量子产率的常规设备只能测量 1100 nm 以内的波长范围。通过该系统,在高达 1650 nm 的宽波长范围内可以对量子产率进行绝对测量,并增加了 NIR PL 测量单元,该单元在近红外中配备了灵敏的 InGaAs 线阵传感器。
①NIR PL 测量单元 C13684-01
用于近红外(900 nm 至 1650 nm)测量的多通道探测器。包括灵敏度校准数据。
该系统由 Quantaurus-QY Plus (C13534-11、-12) 组成,并添加了一些补充单元:一个 NIR PL 测量单元、一个大功率氙气灯单元和一个滤波器单元。
对于过去用于测量绝对 PL 量子产率的设备,通常从根本上难以评估低量子产率(例如,1% 或更低)。该系统通过使用高输出氙气灯作为激发光源,可以评估 1% 或更低的低量子产率。它对于将测量波长范围扩展到近红外区域特别有效。
