Evaluating the Luminous Efficiency of Solid-State Semiconductor Materials
A 100 mm diameter Spectralon integrating sphere unit was used to measure the fluorescence quantum efficiency of the light-emitting layer of a
solid-state semiconductor material (tris(8-hydroxyquinolinato)aluminum) used in an organic EL device.
Using the quantum efficiency measurement application of LabSolutions RF software allows determining the fluorescence quantum efficiency
easily using intuitive software commands.
The integrating sphere unit fits completely
inside the sample compartment, eliminating the
need for additional installation space.

Measuring the Fluorescence Quantum Efficiency of Solution Samples
In addition to film and powder samples, the
integrating sphere can secure a cuvette for
measuring liquid samples.
The fluorescence quantum efficiency of a 1 N
aqueous sulfate solution of quinine sulfate was
measured (on an NIST SRM 936a substrate). Even
tedious fluorescence quantum efficiency
calculations can be performed readily using the
LabSolutions RF quantum efficiency measurement
function.
