Cadmium sulphide (CdS) or selenide materials have been around for some time but cadmium is problematic in the environment and avoided in new materials technologies. QustomDot have a solution (literally). Their indium phosphide (InP) dots have high efficiency and avoid the use of harmful cadmium. By controlling the size of the nano-particles, they are able to change the colour of light the quantum dots emit. InP based dots can be produced not only in solutions but also transferred to surfaces such as those of gallium nitride microLEDs.<\/p>\t\t\t\t\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-top-section elementor-element elementor-element-543efd4 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"543efd4\" data-element_type=\"section\" data-e-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-100 elementor-top-column elementor-element elementor-element-1864c5a\" data-id=\"1864c5a\" data-element_type=\"column\" data-e-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-effe5ea elementor-widget elementor-widget-text-editor\" data-id=\"effe5ea\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Partners MICLEDI, a spin-out from the Belgian microelectronics hub at IMEC, are able to produce the required wafer-scale GaN microLEDs.
