TL;DR: In this paper, the wavelength for heavy atom enhanced phosphorescence was unambiguously established by time resolved excitation spectra in 50% EPA and 50% ethyl iodide at 77 K for protoporphyrin (795 nm), mesoporphrin (773 nm), octaethylporphin (768 nm), and porphin (785 nm).

TL;DR: In this article, the quenching of the emission from a luminescent (phosphorescent of fluorescent) molecule embedded in an oxygen-permeable matrix is used to measure oxygen concentration.

TL;DR: In this paper, the authors demonstrated the feasibility of using the oxygen dependence of luminescent molecules for surface pressure measurement in aerodynamic testing, based on the observation that the light emitted increases as the oxygen partial pressure, and thus the air pressure, the molecules see decreases.

TL;DR: Chloro−phenoxo− (octaethylporphinato)chromium(III) shows relatively normal visible (Q) bands in the region 610−500 nm and a relatively normal Soret (B) band at 447 nm; in addition, there are prominent near uv region 400−300 nm (2×104 < e < 3×104 M−1⋅cm−1) and clear near ir bands in this paper.

TL;DR: The octaethylporphin complexes of forms (OEP)MXnLm, OEP)MO, and OEPM(O)X (M = Sc(Ill), Ti(lV), Zr(IV), Hf(JV), Nb(V), and Ta(V); X = univalent anion; L = neutralligandJ all show fluorescence and phosphorescence, as does the tetraphenylporphine complex (TPP)ScX as mentioned in this paper.
