Confocal microphotoluminescence of InGaN-based light-emitting diodes
Spatially resolved photoluminescence PL of InGaN/GaN/AlGaN-based quantum-well-structured light-emitting diodes LEDs with a yellow-green light 530 nm and an amber light 600 nm was measured by using confocal microscopy. Submicron-scale spatial inhomogeneities of both PL intensities and spectra were found in confocal micro-PL images. We also found clear correlations between PL intensities and peak...
متن کاملConfocal microscopy using an InGaN violet laser diode at 406nm.
We report on the application of a novel all-solid-state violet laser diode source to confocal microscopy. The source has the potential to replace argon ion lasers in a range of fluorescence based imaging systems. Improvements in system performance and image quality through the use of anamorphic prisms to modify the beam profile have been characterised. These modifications have permitted high qu...
متن کاملMulti-confocal fluorescence correlation spectroscopy.
We report a multi-confocal Fluorescence Correlation Spectroscopy (mFCS) technique that combines a Spatial Light Modulator (SLM), with an Electron Multiplying-CCD camera (EM-CCD). The SLM is used to produce a series of laser spots, while the pixels of the EM-CCD play the roles of virtual pinholes. The phase map addressed to the SLM, calculated by using the spherical wave approximation, makes it ...
متن کاملSub-microscopic transient lens spectroscopy of InGaN/GaN quantum wells
Transient lens (TL) spectroscopy was developed with sub-micrometer spatial resolution to observe the temporal and special behavior of the nonradiative processes of carrier dynamics in InGaN/GaN quantum wells (QW). We have observed the carrier density dynamics and the thermal dynamics in the TL signals with a nanosecond pulsed laser. We have also observed TL and photoluminescence (PL) signals by...
متن کاملDepth-resolved confocal micro-Raman spectroscopy for characterizing GaN-based light emitting diode structures.
In this work, we demonstrate that depth-resolved confocal micro-Raman spectroscopy can be used to characterize the active layer of GaN-based LEDs. By taking the depth compression effect due to refraction index mismatch into account, the axial profiles of Raman peak intensities from the GaN capping layer toward the sapphire substrate can correctly match the LED structural dimension and allow the...
