Eu(2+)-doped Ba3Si6O12N2 phosphors were prepared successfully via a modified solid-state diffusion method. The phosphors were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence measurements. These phosphors were effectively excited at 355 nm and an intense emission peaking in the range 480 nm to 525 nm in the blue region was observed. The optimized dopant concentration was determined to be 1 mol% of Eu(2+) ion. The colour coordinates for phosphor were found to be (0.196, 0.326) in the blue region. This phosphor may find application for near-ultraviolet (NUV) excited lamp phosphors. The thermoluminescence study shows the complex glow curve. Trapping parameters (activation energy and frequency factor) were calculated for individual deconvoluted peaks by Chen's peak shape method, the initial rise method and the whole glow peak method.

“…Recent years, as a candidate of green phosphors to be used in the white light-emitting diodes, one promising oxynitride phosphor material, Ba 3 Si 6 O 12 N 2 :Eu 2þ (BSON), has been studied by many researchers [1][2][3][4][5][6]. They reported the crystal structure [2,4], the intense green PL with good color rendering index [1], the high internal quantum efficiency (IQE) [4] and good thermal stability [2] and so on.…”

“…They reported the crystal structure [2,4], the intense green PL with good color rendering index [1], the high internal quantum efficiency (IQE) [4] and good thermal stability [2] and so on. Though there still exists a possibility to improve the IQE by reducing defects, detailed characterization of defect levels which act as nonradiative recombination (NRR) centers and deteriorate IQE in BSON phosphor has not yet been accomplished.…”

Tuning the mechanical and physicochemical properties of cross‐linked protein films

2019

Films derived from natural sources such as proteins provide an advantage over synthetic films due to their noncytotoxicity, biodegradability, and vast functionality. A new protein source gained from the cataractous eye protein isolate (CEPI) obtained after surgery has been investigated for this purpose. Glycerol has been employed as the plasticizer and glutaraldehyde (GD) as a cross‐linker. Fourier transform infrared spectroscopy was employed to characterize the films. Nanoindentation and thermogravimetric analyses reveal improved mechanical and thermal properties of the cross‐linked films. The films with 20% (w/w) GD exhibited properties such as the highest modulus and low water solubility. It is possible to tune the properties based on the extent of cross‐linking. All the films were completely degraded by the enzyme trypsin. The similarity of these films was checked by using the prepared films as a delivery vehicle for a model compound, ampicillin sodium. The encapsulation efficiency was found to be 74%, and in vitro release studies showed significant amounts of drug release at physiological pH. This study will help us understand how the properties of protein films can be tuned to obtain the desired physicochemical properties. These biodegradable protein films could find use in pharmaceutical industries as delivery carriers.
