The effect of chemical composition and structure on Stokes shift, an important luminescence
property, has not been studied systematically. In this work, through statistical analysis of the …

Glass-ceramics (GCs) are constituted by nanometer-to-micron-sized crystals embedded in a
glass matrix; usually, their structural or functional elements (clusters, crystallites or …

The bright red emissive nature of low-cost Mn4+ ions can replace the commercially
available Eu2+-doped nitrides/oxynitrides for application in white light-emitting diodes (W …

Potassium gadolinium fluoride (KGdF 4) up-conversion nano particles (UCNPs) doped with
ytterbium (Yb 3+) and co-doped with erbium (Er 3+) ions were prepared via wet chemical …

This paper deals with the synthesis of cubic phase KYF 4: Eu 3+ nanophosphors via wet
chemical route. Morphological studies such as XRD, SEM and EDAX map** were done to …

Rare earth ion-doped upconversion materials show great potential applications in optical
and optoelectronic devices due to their novel optical properties. In this work, the NaYF4 …

Abstract Potassium Gadolinium Fluoride (KGdF 4) Up-Conversion Nano Particles (UCNPs)

Systematic and strong rare-earth photoluminescence (PL) color flips that are highly sensitive
to structural phase transformation in KLaF4: RE3+ (RE3+= Eu3+, Er3+/Yb3+) nanocrystals …

Nanocrystallisation of the cubic and hexagonal polymorphs of KLaF4 in a 70SiO2–7Al2O3–
16K2O–7LaF3 (mol%) glass has been achieved by heat treatment above the glass transition …

Heavily doped nanocrystals of host KLaF4 with rare earth (RE3+= Er3+, Tm3+, and Yb3+)
ions prepared by a simple one-step template-free wet-chemical route have been reported …
