However, the representation of PL results is often incorrect leading to incorrect conclusions. In 2013, Mooney and Kambhampati reviewed the proper Jacobian transformations for quantitative analysis of emission spectra . To analyze PL results, firstly, the wavelength should be transformed into energy by eqn. (1). Secondly, this conversion of wavelength to energy should preserve the emission spectra area as eqn. (15) because the intensity vs. energy system (IE) is higher at lower energy and vice versa. In other words, the intensity vs. wavelength system (Iλ) should transform into IE as eqn. ( )
