Temperature-Dependent Absolute Photoluminescence Quantum Yield (PLQY) Measurements of a Halide Perovskite

Halide perovskites are a promising class of materials for a wide variety of optoelectronic applications such as photovoltaics, light emitting diodes, lasers and optical sensing. They have received widespread attention due to their many attractive synthetic and photophysical properties, namely: solution processability, high tunability, long charge carrier lifetimes and high charge carrier mobilities.
In Edinburgh’s latest application note, the temperature dependence of the PLQY of a halide perovskite was measured using the cryosphere variable temperature integrity sphere for Edinburgh Instrument’s FLS1000.

Key Takeaways:

– Halide Perovskite PLQY measured using variable temperature integrating sphere

– PLQY increased with decreasing temperature due to suppression of recombination
