Three new 3D Mn(II)-MOFs have been synthesized via solvothermal reaction with MnCl2•4H2O and [1,1':4',1''-terphenyl]-2',4,4'',5'-tetracarboxylic acid (H4tptc) in three different solvents...
View ArticlePlasma induced enhancement of UV photoluminescence of ZnO nanowires
Photoluminescence emission of ZnO nanowires was modified by mean of plasma etching, inducing a strong increase in Near Band Edge emission (NBE) in the UV (3.26 eV). On reverse, annealing treatment at...
