ODPL measurement system
The ODPL measurement system uses an integrating sphere to measure the spectrum of omnidirectional photoluminescence and determine the emission efficiency of samples. This process is non-destructive and non-contact, and can instantly calculate IQE (internal quantum efficiency). IQE is necessary for quality evaluation of GaN single crystals, which have attracted attention as power device materials. It is also necessary for quality evaluation of perovskite crystals, which are expected to be useful for improving the efficiency of solar power generation and LEDs.
