The phrase "a low quantum" is correct and usable in written English.
It can be used in contexts discussing measurements, quantities, or levels, particularly in scientific or technical discussions.
Example: "The experiment showed a low quantum of energy transfer, indicating inefficiency in the process."
Alternatives: "a small amount" or "a minimal quantity".
We also observed an increased intensity and blue spectral shift for the protein human glyoxalase, which displays a low quantum yield for its intrinsic tryptophan emission.
We show that our design can overcome the losses normally incurred due to a low quantum yield emitter by transferring the absorbed energy to a linked fluorophore with a higher quantum yield.
We synthesized this assembly by connecting a low quantum yield (less than 1%) BODIPY donor to a high quantum yield BODIPY acceptor via a 1, 3-triazine bridge system.
The emission spectra of DTH-Fe3O4@SiO2, which is excited at 397 nm, exhibit the emission maximum at 452 nm with a low quantum yield (Φ = 0.0042) at room temperature in ethanol.
However, the practical application of single bare TiO2 in the industry is still a challenge due to the high-rate recombination of photogenerated electrons and holes at the surface of TiO2 results in a low quantum efficiency.
Additional disadvantages include properties such as a low quantum yield (QY) [2], inefficient maturation [3], or suboptimal excitation by existing illumination sources [4] [6].
The first construct made was cpT-Sapphire145-144, whoweverwever had a comparably low quantum yield and extinction coefficient (Table 1) and with a pKa of 5.6 also sacrificed some of the good pH-properties of T-Sapphire.
For example, Domen and co-workers reported that g-C3N4 photosensitized by magnesium II) phthalocyanine showed photocatalytic H2 production activity under visible light irradiation up to 700 nm, but with a rather low quantum efficiency (0.07% at 660 nm)10.
Both processes are associated to a very low quantum efficiency, around 10 8.
However, a very low quantum efficiency of Si-NCs emission suggests that nonradiative processes should be predominant (k NR >> k R).
Phenylalanine has a very low quantum yield and the fluorescence of tyrosine is almost totally quenched if it is ionized or present near to an amino group, a carboxyl group or a tryptophan.
