Photoluminescence quantum efficiency of Er optical centers in GaN epilayers
We report the quantum efficiency of photoluminescence processes of Er optical centers as well as the thermal quenching mechanism in GaN epilayers prepared by metal-organic chemical vapor deposition. High resolution infrared spectroscopy and temperature dependence measurements of photoluminescence intensity from Er ions in GaN under resonant excitation excitations were performed. Data provide a ...
متن کاملOptical Excitation of Er Centers in GaN Epilayers grown by MOCVD
In this paper we present results of photoluminescence (PL), photoluminescence excitation (PLE), and time resolved PL spectroscopy of the I13/2 → I15/2 transition in Er optical centers in GaN epilayers grown by metal-organic chemical vapor deposition. Under resonance excitation via the higher-lying inner 4f shell transitions and band-to-band excitation of the semiconductor host, the PL and PLE s...
متن کاملOptical excitation and external photoluminescence quantum efficiency of Eu3+ in GaN
We investigate photoluminescence of Eu-related emission in a GaN host consisting of thin layers grown by organometallic vapor-phase epitaxy. By comparing it with a reference sample of Eu-doped Y₂O₃, we find that the fraction of Eu(3+) ions that can emit light upon optical excitation is of the order of 1%. We also measure the quantum yield of the Eu-related photoluminescence and find this to rea...
متن کاملPhoto-induced Doping in GaN Epilayers with Graphene Quantum Dots.
We demonstrate a new doping scheme where photo-induced carriers from graphene quantum dots (GQDs) can be injected into GaN and greatly enhance photoluminescence (PL) in GaN epilayers. An 8.3-fold enhancement of PL in GaN is observed after the doping. On the basis of time-resolved PL studies, the PL enhancement is attributed to the carrier transfer from GQDs to GaN. Such a carrier transfer proce...
متن کاملhermal quenching of photoluminescence from Er-doped GaN thin films
The green (537 and 558 nm) and near infrared (1.54 mm) photoluminescence (PL) spectra of Er-doped GaN thin films have been investigated as a function of temperature, excitation wavelength, and pump intensity. Thermal quenching measurements showed that the 31 4 2 4 integrated green Er PL intensity ( S / H → I ) remained nearly constant up to 150 K, but decreased at higher temperatures 3 / 2 11 /...
