Photoluminescence, chemiluminescence and anodic electrochemiluminescence of hydrazide-modified graphene quantum dots.

Nanoscale

Dong Y, Dai R, Dong T, Chi Y, Chen G.
PMID: 25132204
Nanoscale. 2014 Oct 07;6(19):11240-5. doi: 10.1039/c4nr02539c.

Single-layer graphene quantum dots (SGQDs) were refluxed with hydrazine (N2H4) to prepare hydrazide-modified SGQDs (HM-SGQDs). Compared with SGQDs, partial oxygen-containing groups have been removed from HM-SGQDs. At the same time, a lot of hydrazide groups have been introduced into...

Here, we report highly enhanced electrochemiluminescence (ECL) of luminol in the presence of H2O2 on indium tin oxides (ITOs) modified with both of dendrimer-encapsulated Pt nanoparticles (Pt DENs) and chemically converted graphenes (CCGs). The ITO electrodes were electrochemically modified...

Dissipative vector soliton in a dispersion-managed fiber laser with normal dispersion.

Applied optics

Wang S, Fan X, Zhao L, Wang Y, Tang D, Shen D.
PMID: 25608062
Appl Opt. 2014 Dec 10;53(35):8216-21. doi: 10.1364/AO.53.008216.

We numerically study the vector dynamics of dissipative solitons (DSs) in a 2 μm dispersion-managed fiber laser mode locked by a semiconductor saturable absorber mirror and operated in the normal dispersion regime. It is shown that the effective gain...

Miniaturized analytical instrumentation for electrochemiluminescence assays: a spectrometer and a photodiode-based device.

Analytical and bioanalytical chemistry

Neves MM, Bobes-Limenes P, Pérez-Junquera A, González-García MB, Hernández-Santos D, Fanjul-Bolado P.

Herein, a new miniaturized analytical instrumentation for electrochemiluminescence (ECL) assays is presented. A photodiode integrated in an ECL cell combined with a potentiostat/galvanostat, all integrated in a one-piece instrument (μSTAT ECL), was developed. In addition, a complementary micro-spectrometer integrated...
