DOI: 10.1021/acs.jctc.2c00302
Abstract: Excited-state absorption (ESA) spectra of π-conjugated compounds are frequently calculated by (quadratic response) time-dependent density functional theory, (QR) TD-DFT, often giving a reasonable representation of the experimental results despite the (known) incomplete electronic description. To… read more here.

DOI: 10.1039/c9nr09740f
Abstract: Current luminescence nanothermometry exploits either temperature dependent quenching, temperature dependent energy transfer or thermal equilibrium between two metastable emitting levels, which are quantified to convert spectral features into absolute temperature. Although widely used and feasible,… read more here.

DOI: 10.1063/5.0050767
Abstract: Efficient nanoprobes with unique optical properties are highly desirable for good-performance photoacoustic (PA) molecular imaging. The conventionally used PA nanoprobes basically take their ground-state absorption with contrast to the indelible wideband background absorption as the… read more here.

DOI: 10.1364/ao.440736
Abstract: At various temperatures, ranging from 25°C to 50°C, we characterized two types of photodetectors based on surface-state absorption in silicon: (1) contactless integrated photonic probes (CLIPPs) and (2) normal-incidence photoconductors. Both types of photodetectors exhibited… read more here.
