Journal ArticleDOI
Effect of SnO2 concentration on the tuning of optical and electrical properties of ZnO-SnO2 composite thin films
TL;DR: In this article, the structural, optical, and electrical properties of the composite films have been studied as a function of SnO2 content, and it is revealed from X-ray diffraction analysis that films are crystalline in nature and the crystallite size decreases from 20-23nm to 5-7nm with increase of Sn O2 content.
Journal ArticleDOI
Effect of Al doping on structural, optical and electrical properties of SnO2 thin films synthesized by pulsed laser deposition
TL;DR: In this article, structural, optical and electrical properties of the as-deposited and post-annealed thin films were investigated and X-ray diffraction patterns suggest that the films transform from crystalline to amorphous state with increasing aluminium content.
Journal ArticleDOI

Samit K. Ray,Kristian M. Groom,R.R. Alexander,Kenneth Kennedy,Huiyun Liu,Mark Hopkinson,Richard A. Hogg +6 more
TL;DR: In this article, a technique for broadening the emission and gain spectra of 1.3μm quantum dot superluminescent light emitting diodes (SLEDs) is discussed.
Journal ArticleDOI
Tuning Emission Properties via Aromatic Guest Inclusion in Organic Salts Composed of 4,4′-Dinitro-2,2′,6,6′-tetracarboxybiphenyl and Acridine
TL;DR: An organic salt composed of 4,4′-dinitro-2,2′,6,6′-tetracarboxybiphenyl and acridine has been shown to act as host to accommodate large polyaromatic guest molecules.
Journal ArticleDOI
Effect of Fungicides and Insecticides on Growth and Enzyme Activity of Four Cyanobacteria
TL;DR: Cyanobacterial populations introduced into crop fields as biofertilizer become non-target organisms for the pesticides and fungicides applied in the field and cell free extracts of cyanobacteria treated with pesticides show a drastic reduction of ICDH activity.
