Графитоподобный нитрид углерода – двумерный флуоресцентный материал с выявленной деградацией флуоресцентных свойств. Он был получен термическим разложением меламина и исследован с помощью ИК спектроскопии, просвечивающей электронной микроскопии и рентгенофазового анализа. Выявлено три основных механизма деградации флуоресценции. Первый и третий – это присоединение водорода к центрам с неподелённой парой электронов, что приводит к критическому изменению флуоресцентных свойств, а второй – адсорбции воды, которая накапливается не только по поверхности материала, но и, возможно, проникает между слоёв, вызывая этим незначительное ухудшение флуоресценции.
