RSC Advances is delighted to announce a new themed collection titled ‘Photoluminescence of lanthanide-doped phosphor materials’. This collection is Guest Edited by Dr Ram Sagar Yadav (Banaras Hindu University), Prof. Bryce S. Richards (Karlsruhe Institute of Technology), Professor Joanna Pisarska (University of Silesia) and Professor Xinyu Ye (JiangXi University of Science and Technology).
Scope:
The aim of this collection is to focus on the synthesis, as well as the structural and optical properties, of different types of lanthanide-doped phosphor materials, such as phosphors, nano-phosphors and phosphor composites. This collection welcomes primary research articles as well as review articles, related to the synthesis, characterization and applications of different types of the lanthanide-doped phosphor materials.
The lanthanide ions can produce multicolor photoluminescence, and contain various distinct energy levels in which some are meta-stable. Each energy level can be excited with a certain excitation wavelength, with the emitted light of lanthanide ions covering emissions in the ultraviolet, visible and near infrared regions. Due to the various properties of lanthanide ions, lanthanide-doped phosphor materials can be utilised for different technological applications in various fields, such as display devices, red-green-blue (RGB) emitting materials, light emitting diodes (LEDs), phosphor-converted LEDs (pc-LEDs), white LEDs, solar cell, optical heating, temperature sensing and bio-imaging.
Lanthanide ions also enable upconversion (UC) and downconversion (DC) of photons. The UC process is helpful for measuring the temperature sensing sensitivity of different phosphor materials, as it depends on the fluorescence intensity ratio (FIR) of the two thermally coupled (TC)/non-thermally coupled (NTC) emitting levels. In these cases, the emission intensity of one level is found to increase while that of the other decreases when the external temperature of the sample is increased, and vice-versa. This generates lattice vibration in the host lattice, which initiates a shift in the population of the excited ions from one level to the other. The plot between FIR-based sensitivity and external temperature gives temperature sensing, which can be examined in the other lanthanide-doped phosphor materials.
The aim of this collection is to focus on the synthesis, as well as the structural and optical properties, of different types of lanthanide-doped phosphor materials, such as phosphors, nano-phosphors and phosphor composites. This collection welcomes primary research articles as well as review articles, related to the synthesis, characterization and applications of different types of the lanthanide-doped phosphor materials.
