Judd-Ofelt analysis of luminescence spectra of an erbium chloride-doped carboxy methyl cellulose film

Optical absorption and photoluminescence properties of an ErCl 3 -doped carboxy methyl cellulose film have been studied. From measured intensities of various absorption bands of film, the Judd-Ofelt parameters Ω 2 , Ω 4 and Ω 6 have been calculated. The Judd-Ofelt theory has been applied to characte...

Description
Summary:Optical absorption and photoluminescence properties of an ErCl 3 -doped carboxy methyl cellulose film have been studied. From measured intensities of various absorption bands of film, the Judd-Ofelt parameters Ω 2 , Ω 4 and Ω 6 have been calculated. The Judd-Ofelt theory has been applied to characterize the photoluminescence spectra of the investigated film. From this theory, various radiative properties, such as transition probability A T , branching ratio β r , radiative life time τ r and emission cross section , for various emission levels have been determined and reported.
