Room‐Temperature Phosphorescence Emitters Exhibiting Red to Near‐Infrared Emission Derived from Intermolecular Charge‐Transfer Triplet States of Naphthalenediimide−Halobenzoate Triad Molecules

We studied the effect of solvent vapours on the photoluminescent emission of self-assembled InP surface quantum dots (SQDs). Their room temperature near infrared emission undergoes a fully reversible intensity enhancement when the dots were exposed to vapours of polar solvents since polar molecules are likely to be adsorbed onto intrinsic surface states and thus reducing non radiative surface recombination. The shape and position of the emission band does not change. The observed effect is dependent on solvent type and concentration with linear law over a limited concentration range.

Near Infrared Emission

A tellurite glass of TeO2-PbO-Li2O doped with Nd2O3 has been successfully fabricated by using the conventional melt-quenched technique. The absorption and emission spectroscopy have been identified using UV-VIS-NIR and photoluminescence spectrometer, respectively. From the spectroscopy, ten significant spectra have been observed in the region of 400-900 nm. The absorption wavelength centered at 585 nm attributed to 4I9/2 → 4G5/2 transition is the predominant wavelength to be used as the excitation wavelength. Emission spectra have been determined by using 585 nm excitation wavelength at room temperature. From the emission spectra, seven distinctive upconversion bands contributed from Nd3+ were observed in the region of 400-1500 nm. It was found that the bands were centered at 450 nm (4G11/2 → 4I9/2), 485 nm (4G11/2 → 4I11/2), 605 nm (4G11/2 → 4I15/2), 665 nm (4G7/2 → 4I13/2), 880 nm (4F3/2 → 4I9/2), 1062 nm (4F3/2 → 4I11/2) and 1340 nm (4F3/2 → 4I11/2), respectively. Tthese emission bands showed the possibility of visible and near infrared emission spectra.
