Using Low Temperature Photoluminescence Spectroscopy to Investigate CH$_3$NH$_3$PbI$_3$ Hybrid Perovskite Degradation

Investigating the stability and evaluating the quality of the CH$_3$NH$_3$PbI$_3$ perovskite structures is quite critical both to the design and fabrication of high-performance perovskite devices and to fundamental studies of the photophysics of the…

Side-Chain Metallopolymers Containing Second-Order NLO-Active Bimetallic Ni-II and Pd-II Schiff-Base Complexes: Syntheses, Structures, Electrochemical and Computational Studies

Unsymmetric Schiff-base metalloligand precursor 2 is synthesized by condensation of phenol-functionalized ferrocenylenaminone 1 with 2-hydroxy-5-nitrobenzaldehyde. Heterobimetallic complexes 3 and 4 result from the N2O2-tetradentate coordination of…

Thermodynamics study of the noncovalent functionalization of surfactant suspended graphene nanosheets with porphyrin molecules

We report on the noncovalent functionalization of graphene with hydrophobic tetraphenyl porphyrin (TPP) molecules in micellar aqueous suspensions. We study the thermodynamical parameters of the reaction using optical spectroscopy, and measure its…

Single layer nano graphene platelets derived from graphite nanofibres

Solutions of calibrated nanographenides (negatively charged nanographenes) are obtained by dissolution of graphite nanofibre intercalation compounds (GNFICs). Deposits show homogeneous unfolded nanographene platelets of 1 to 2 layers thickness and…

Coherent Population Trapping of a Single Nuclear Spin Under Ambient Conditions

Coherent control of quantum systems has far-reaching implications in quantum engineering. In this context, coherent population trapping (CPT) involving dark resonances 1,2 has played a prominent role, leading to a wealth of major applications…

Evidence for near-infrared photoluminescence of nitrogen vacancy centers in 4 H -SiC

We present evidence of near-infrared photoluminescence (PL) signature of nitrogen vacancy centers (NCVSi)− in silicon carbide (SiC). This center exhibits an S=1 ground state spin similar to the NV− center in diamond. We have performed…
