  Abstract


Abstract: Lanthanum fluoride (LaF3:Ce3+, Pr3+, Sm3+) synthesized by water soluble LaCl3 + CeCl3+ PrCl3 + SmCl3 and NH4F as starting materials in de-ionized water as solvent using microwave assisted technique. The structure of LaF3:Ce3+, Pr3+, Sm3+ nanocrystals analyzed by XRD and TEM analysis is found to be in hexagonal structure and average crystalline particle size is 20 nm (JCPDS standard card (32-0483) of pure hexagonal LaF3 crystals). The absorption edge in UV spectra is found at 250 nm corresponding to energy of 4.9eV. It further shows a wide transparent window lying between 200 nm - 800 nm. For LaF3; Ce3+, Pr3+, Sm3+ nanocrystals emission of blue color (458 nm) has been observed with at an excitation wavelength of 254 nm. The measured relative second harmonic generation (SHG) efficiency of LaF3: Ce3+, Pr3+, Sm3+ in de-ionized water with respect to KDP crystal is 0.186.
