Luminescence of the Alkali-Metals Nitrites Incorporated into Cellulose Matrix

Abstract

Surface morphology and photoluminescence (PL) properties of both microcrystalline cellulose (MCC), microcrystalline powders of the alkali metals nitrites MNO2 (M = Na. K, Cs) (MCN) and two-component composite materials based on the MCC and MCN have been studied and characterized by means of optical microscopy and luminescence spectroscopy.

Structure and Properties of Microcrystalline Cellulose "Ceramics-Like" Composites Incorporated with LaVO4:Sm Oxide Compound

“…The described data are similar to ones earlier reported by us for the microcrystalline cellulose samples and some other "cellulose-oxide" composites [12,13,16]. Besides, mentioned characteristics are similar to those published elsewhere concerning luminescence of various cellulosebased materials [5,[8][9][10].…”

“…At the same time, they are of interest as materials for applications in electronic and opto-electronic devices, e.g. such as solar cells, supercapacitors, lithium-ion batteries, flexible "paper" electronics [5][6][7] and luminescent materials [8][9][10] particularly for their potential applications as chemical and biological sensors or for toxic chemical removing [11][12][13].…”

Polymer-Oxide Composites: Toward New Optical Materials

“…We denote the composites of such type here as W-NaNO 2 and W-CsNO 3 . The details both of the oxides synthesis and the samples preparation can be found in [36,37,44,48,49].…”

“…Those were scanning electron microscopy (SEM), chemical elements analysis, X-ray diffractometry (XRD), luminescence spectroscopy and dielectric characteristics measurements. Equipment and any other details of experimental study can be found also in [36,37,44,48,49].…”

“…These PMM/NCs are sustainable and renewable materials and paid great attention in biomedical technologies (membranes and filters, scaffolds, antimicrobial films, pharmaceuticals, drugs delivery, etc. [31][32][33][34]) or as adsorbents for toxic chemicals removing [35][36][37]. Due to their mechanical flexibility they can be useful in manufacturing of the electronic and opto-electronic devices (solar cells, super-capacitors, lithium-ion batteries, "paper" electronics [38][39][40], luminescence sensors [41][42][43]).…”
