High-contrast multi-surface imaging of latent fingerprints using color-tunable YOF:Tb,Eu ultrafine nanophosphors with high quantum yield.

Visualization of latent fingerprints (LFPs) using conventional powders has faced challenges on multicolor surfaces. However, these challenges are addressed by the advent of fluorescent powders in LFP detection, and they have redefined the effectiveness of the powder dusting method. In this study, color-tunable YOF:Tb,Eu nanophosphors were examined for LFP recognition and were evaluated for their practicality on different types of surfaces.

Influence of Li charge compensator ion on the energy transfer from Pr to Gd ions in CaMg(PO)F:Gd, Pr, Li phosphor.

Phototherapy is a renowned treatment for curing skin diseases since ancient times. Phototherapeutic treatment for psoriasis and many other diseases require narrow band ultra violet-B (NB-UVB) light with peak intensity at 313nm to be exposed to the affected part of body. In this paper, we report combustion synthesis of NB-UVB -313nm emitting CaMg(PO)F phosphors doped with Gd, Pr and Li ions.

Synthesis and Luminescence Characterization of LaBO:Dy Phosphor for Stress Sensing Application.

LaBO:xDy (x = 0.05 mol%, 0.1 mol%, 0.

Photoluminescence and electron paramagnetic resonance properties of a potential phototherapic agent: MMgF :Gd (M = Ba, Sr) sub-microphosphors.

Novel narrow band UVB-emitting phosphors, BaMgF :Gd and SrMgF :Gd phosphors, were synthesized using a co-precipitation synthesis method. X-Ray diffraction analysis was carried out to confirm compound formation, phase purity and crystallinity of the phosphor. At 274 nm excitation, phosphors show a sharp narrow band emission at 313 nm that can be assigned to P  →  S transition of the Gd ion.

Investigation of UV-emitting Gd(3+)-doped LiCaBO3 phosphor.

Incorporating the Gd(3+) rare earth ion in the LiCaBO3 host lattice resulted in narrow-band UV-B emission peaking at 315 nm, with excitation at 274 nm. The LiCaBO3:Gd(3+) phosphor was synthesized via the solid-state diffusion method. The structural, morphological and luminescence properties of this phosphor were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) and photoluminescence (PL) spectroscopy.
