High-Brightness White-Light Source Based on Up-Conversion Phosphors

Luminescent Activator Dy3+ Ion in Auto-Combusted Nanosized La (OH) 3

“…The former is mainly applied in lighting and display fields like cathode ray tubes (CRTs), plasma display panels (PDPs), filed emission displays (FEDs) and so on. The latter has several advantages in the field of biomedicine [12]. However, the efficiency of the fabricated device depends strongly on the material chemical composition, crystal structure, shape, and dimensionality of the host material which are sensitive to the bonding states of rare earth ions.…”

Oxygen influence on luminescence properties of rare-earth doped NaLaF 4

“…Moreover, UC luminescent RE doped fluorine materials are promising materials for various future applications such as optical signal amplification and different light sources [8,9]. Fluorine materials have the benefit of a small phonon energy, which leads to decreased rate of non-radiative transitions [10].…”

Three primary colors upconversion phosphors and combined white upconversion luminscence in Y2O2S matrix

“…Firstly, red, green and blue upconversion luminescent materials can be mixed in accordance with a certain proportion. J. Milliez et al [16] produced a high-brightness white-light source based on red, green and blue up-conversion phosphors with the chromaticity coordinate of (0.3127, 0.3297). X.X.…”
