WebThe fluorescence quantum yield of N-CQDs obtained under these conditions was 32.64%. Under the excitation of light at a wavelength of 365 nm, the emission peak of N-CQDs was located at 430 nm and emitted blue light. The prepared cellulose and nanocellulose were mixed with N-CQDs respectively, ... WebThe fluorescence quantum yield, which is the ratio of the number of fluorescence photons emitted (Stage 3) to the number of photons absorbed (Stage 1), is a measure of the relative extent to which these processes …
