Abstract
Here, we report the bright white light emission from Eu3+ doped In2S3 nanoparticles by single wavelength light excitation (350 nm). The energy transfer (ET) from the In2S3 host to the Eu3+ ions is studied by steady-state and time-resolved spectroscopy. It is found that the ET efficiency from In2S3 nanoparticles to Eu3+ increases from 0.27% to 0.42% with increasing dopant concentration. The calculated quantum efficiency is 24.2% for 1.0 mol% Eu doped In2S3 nanoparticle and the CIE coordinates are 0.27 and 0.29, which fall within the white region of the 1931 CIE diagram.
