Ht24s 24w metal ceramic heater

The morphology and composition of the samples were studied using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The SEM image and EDS spectra were obtained using a Hitachi SU3500. Crystal structures were identified by X-ray diffraction (XRD) analysis. The XRD patterns were obtained using an Equinox1000 Sn.1612EQ1000137 diffractometer (Thermo Fisher; Horten, Norway) with Cu Kα radiation (λ = 1.5418 Å). The optical absorption spectrum was measured using a UV-2600 photo spectrometer (Shimadzu; Horten, Norway). The emission, excitation spectra, and electronic lifetime were measured using an Edinburgh FS05 Fluorescence Spectrometer. The quantum efficiency was measured with a calibrated AvaSpec-ULS2048-EVO PL spectrometer and AvaSphere-50 integrating sphere. In the thermal quenching experiment, samples were heated over a HT24S-24W metal ceramic heater (ThorLabs) and temperature-dependent photoluminescence was measured using the Edinburgh FS05 fluorescence spectrometer.

We investigated the morphology, particle size, composition, and crystal structures of our samples through the use of Hitachi SU3500 for obtaining SEM images and EDS spectra. Our identification of crystal structures was based on X-ray diffraction patterns obtained from an Equinox1000 Sn.1612EQ1000137 diffractometer (Thermo Fisher; Horten, Norway), which utilized Cu Kα radiation (λ = 1.5418 Å). Furthermore, we measured the emission and excitation spectra using an Edinburgh FS05 Fluorescence Spectrometer, and determined the quantum efficiency via a calibrated AvaSpec-ULS2048-EVO PL spectrometer and AvaSphere-50 integrating sphere. To assess thermal quenching temperature, our samples were heated with a HT24S-24W metal ceramic heater (ThorLabs). Photoluminescence relative intensity readings were taken at varying temperatures using the Edinburgh FS05 fluorescence spectrometer.
