WebUV-Vis spectroscopy denotes the absorbance or reflectance spectroscopy in the UV or visible region. In UV-Vis spectrum a graph of absorbance vs. wavelength is obtained and it measures the transition from the groud to the excited state. On the other hand photoluminescence deals with the transitions from excited to the ground state.
