Luminescence instrumentation slits

A = absorbance I = relative emission intensity instrument = model LS Perkin Elmer luminescence spectrometer slits = 6 nm fluorescent material = CdTe quantum dots synthesised according to Ref. [66] (aqueous medium 1 6 v/v water dilution before measurements) wavelength for maximum absorption = 467 nm wavelength for maximum emission = 632 nm. 

Q8.16 Why should instrumental parameters (excitation wavelength, slit width, etc.) on the fluorescence spectrophotometer not be changed when measuring luminescence intensities for a given series of solutions ... 

The principle of a sophisticated array-detector-based instrument to produce total luminescence spectra is illustrated in Figure 1.5-12a. Here, the length of a sample cell is irradiated with an excitation beam that has been dispersed along the. ry plane by a monochromator that has been rotated 90 with respect to its exit slit. The transducer is a two-dimensional charge-...
