(NanoLum)<\/strong> is a consequence of continuous evolution, and the focus of research today is wide, but always aiming at luminescent nanostructured systems. Ongoing projects aim to study emission processes via mechanisms such as <em>Downshifting, Upconversion and Downconversion<\/em>. In addition, the synthesis of particles by spray pyrolysis provides the study of materials for Laser emission in a random environment. Thus, the group works on the synthesis of nano and sub microparticulate inorganic materials with control of the crystal structure to explore the luminescent properties of lanthanide ions, such as alumina, silica, titania, YAG, fluorides, molybdates, and borates; the research has also been carried out in matrices of biological origin, such as bacterial cellulose and fibroin (silk protein extracted from the cocoons of the silkworm, <em>Bombyx mori<\/em>), always aiming for new devices for emitting light, whether in ultraviolet, visible, or infrared.<\/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<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element

YAG and YAB doped with Er3+ or with Yb3+\/Er3+ were also obtained and studies of the thermometric response via upconversion mechanism are ongoing. The development of luminescent materials to act as a gas sensor is one of our focuses of studies; and the basis of this work are silica and alumina aerogels doped with rare-earth ions, as well as fibroin composite films and complexes of Eu3+ ion.\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<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-60a1bb7 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"60a1bb7\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-3f7823d\" data-id=\"3f7823d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-c883712 elementor-widget elementor-widget-image\" data-id=\"c883712\" 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 loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"257\" src=\"https:\/\/sites.usp.br\/nanolum\/wp-content\/uploads\/sites\/1016\/2021\/09\/Image-04-link-Research-objetivo-03-300x257.jpg\" class=\"attachment-medium size-medium wp-image-1366\" alt=\"\" srcset=\"https:\/\/sites.usp.br\/nanolum\/wp-content\/uploads\/sites\/1016\/2021\/09\/Image-04-link-Research-objetivo-03-300x257.jpg 300w, https:\/\/sites.usp.br\/nanolum\/wp-content\/uploads\/sites\/1016\/2021\/09\/Image-04-link-Research-objetivo-03-400x342.jpg 400w, https:\/\/sites.usp.br\/nanolum\/wp-content\/uploads\/sites\/1016\/2021\/09\/Image-04-link-Research-objetivo-03.jpg 484w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/>\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\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-d62a6e4\" data-id=\"d62a6e4\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-f3955fd elementor-widget elementor-widget-heading\" data-id=\"f3955fd\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">3\u00b0) Luminescent composite materials<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-67371e8 elementor-widget elementor-widget-text-editor\" data-id=\"67371e8\" 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>The group is active in the preparation and structural study of composites doped with lanthanide ions involving matrices of biological origin, such as bacterial cellulose, gellan gum, and fibroin (silk protein extracted from silkworm cocoons, <em>Bombyx mori<\/em>), to obtain new materials for application in photonics.
