Abstract
Rare earth ions Er3+, La3+, and Y3+ have been introduced into the lattice of CdS nanobelts (NBs) to modulate its radiative recombination rate (RRR) during photoluminescence (PL) process. It is found that these ions have different quenching effects on the RRRs of direct interband transition and defect related transition. Only the former is greatly reduced through Er3+ doping, however, both of them are suppressed to a certain extent by La3+ and Y3+ doping. It is valuable that specific solid color luminescence can be realized through well‐chosen rare earth ions.
期刊介绍：
The journal Crystal Research and Technology is a pure online Journal (since 2012).
Crystal Research and Technology is an international journal examining all aspects of research within experimental, industrial, and theoretical crystallography. The journal covers the relevant aspects of
-crystal growth techniques and phenomena (including bulk growth, thin films)
-modern crystalline materials (e.g. smart materials, nanocrystals, quasicrystals, liquid crystals)
-industrial crystallisation
-application of crystals in materials science, electronics, data storage, and optics
-experimental, simulation and theoretical studies of the structural properties of crystals
-crystallographic computing
