“…Holmium-YAG lasers are used for fragmentation of colonic fecalith and kidney stones material. [10][11][12] In oncology, 166 Ho microspheres are used for the radioembolization of liver cancer 13 , hepatocellular carcinoma of liver cancer and bone metastases. 14 Due to good penetration depth, high magnetic moment, emission of βparticles and γ-radiations, 166 Ho 3+ based compounds are used in computed tomography, diagnosis, therapeutic and Magnetic Resonance Imaging.…”

Optical absorption spectra of Holmium (III)-complexes with Indole derivative [viz:1H-indole -3-carboxylic acid, 2-(1H-indole-3-yl)ethanoic acid and 4-(1H-indole-3-yl)butanoic acid] have been analyzed as a doped system in different medium. Micellar effect is sensational to the transition 5G6← 5I8 and become hypersensitive in UV-Visible absorption spectra. Micellar medium of cationic surfactant found be most effective to enhance the intensity of hypersensitive transition. Intensity parameters, Oscillator Strength (P), magnitude was observed somewhat different in the micellar medium as compared to the non-micellar medium. Applicability of Judd Ofelt theory indulged in spectral analysis for various parameters. Judd Ofelt parameters and other covalency parameters are in favour for the existence of covalency and the degree has been raised in micellar medium. Nonionic surfactant (BRIJ35), Cationic surfactant (CTAB), and anionic surfactant (SDS) shows significant interaction, reflects in spectral study of Holmium(III)-Indole derivative complexes.
