Dual-emitter polymer carbon dots with spectral selection towards nanomolar detection of iron and aluminum ions

We report on the spectral selection of excitation wavelength towards selective detection of aluminum and iron ions using dual emission polymer carbon dots (PCDs). PCDs were prepared from glucose and dilute sulfuric acid using one-pot solvothermal method. The PCDs emit blue light at 480 nm when excit...
