In addition to the measurement of emission and excitation spectra of photoluminescence, this equipment also allows the study of photoluminescence decay, thermoluminescence, radioluminescence, X-ray luminescence and optical absorption of materials. Thanks to helium optical cryostats, these measurements can be made at temperatures of 4.2 to 450 K. In addition, a micro-Raman spectrometer with a confocal microscope is available which allows the spatial variation of Raman scattering and photoluminescence emission spectra to be investigated in bulk samples.<\/p><p class=\"MsoNormal\">\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<div class=\"elementor-element elementor-element-f604004 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"f604004\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7914cff elementor-widget elementor-widget-heading\" data-id=\"7914cff\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Main experimental equipment<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b4f8a68 elementor-widget elementor-widget-text-editor\" data-id=\"b4f8a68\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><strong><em>Commercial photoluminescence spectrometer FLS1000<\/em><\/strong><\/p><p>The spectrometer allows the following luminescence characteristics of samples to be measured at room temperature:<\/p><ul><li>Emission spectra in the region 200 - 980 nm when excited with monochromatic light from a high-pressure xenon lamp,<\/li><li>excitation spectra in the region 200 to 1000 nm for emission in the region 200 to 980 nm,<\/li><li>photoluminescence lifetime from 200 ps to 1 s with emission in the 200 - 980 nm region, when excited with a pulsed \"microsecond\" xenon lamp usable in the 200 - 1000 nm region, a pulsed \"nanosecond\" hydrogen lamp usable in the 200 - 400 nm spectral region, or pulsed \"picosecond\" diode lasers (445, 510, 635, 670 nm),<\/li><li>time-resolved emission spectra with selectable delay times,<\/li><li>absolute quantum yield of photoluminescence in the 250 - 980 nm region,<\/li><li>spectral dependence of the optical density or transmission of the sample in the region 200 - 1 000  nm,<\/li><li>the chromatic coordinates of the photoluminescence of the sample according to the CIE 1931 and CIE 1976 standards.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f0fa129 elementor-widget elementor-widget-image\" data-id=\"f0fa129\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"568\" height=\"338\" src=\"https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000.png\" class=\"attachment-medium_large size-medium_large wp-image-5516\" alt=\"\" srcset=\"https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000.png 568w, https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000-300x179.png 300w, https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000-18x12.png 18w, https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000-230x137.png 230w, https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000-350x208.png 350w, https:\/\/kiplweb.fjfi.cvut.cz\/web\/wp-content\/uploads\/2023\/02\/FLS1000-480x286.png 480w\" sizes=\"(max-width: 568px) 100vw, 568px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0bb4775 elementor-widget elementor-widget-text-editor\" data-id=\"0bb4775\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p style=\"margin-bottom: 0.0001pt;
