Description :
Luminescence is a widely used phenomenon in the field of research. It is being studied for the last 4-5 decades. Luminescence used for emission of light works mainly on phenomena of absorption (excitation and emission). There is various theoretical model used for the analysis of luminescence in rare earth-doped inorganic phosphors. But, in this review, will study Judd –Ofelt (JO) parameters used for quantitative determination of optical parameters, transition speed and emission quantum competency. Additionally, it is used to research the local structure and bonding around rare earth (RE) ions. Judd – Ofelt theory has shown to be useful equipment for locating certain transitions of choice. Its main application is to calculate the electric dipole oscillator strength between any states. This article is mainly a review of Judd –Ofelt study from examples published in last 5 years.
