Mn-doped ZnS quantum dots for the determination of acetone by phosphorescence attenuation

“Turn off–on” phosphorescent biosensors for detection of DNA based on quantum dots/acridine orange

“…In additional, the detection selectivity is further enhanced as phosphorescence is less common than fluorescence [17]. The development of RTP sensors shows bright prospect [16][17][18][19][20][21][22][23][24][25][26][27] because any other complicated pretreatments are required for the developed biosensors [18,20,25]. However, there is rare research about the "Turn off-on" of RTP sensors.…”

“…Recently, room-temperature phosphorescence (RTP) QDs detection has attracted much attention and has been widely applied into sensors, especially biomolecular sensors [16][17][18][19][20][21][22][23][24][25][26][27]. Owing to the longer lifetime of phosphorescence, RTP QDs detection provides high reliability and stability without interference from autofluorescence or scattered light [16,[18][19][20].…”

Modified Eu‐doped Y2O3 nanoparticles as turn‐off luminescent probes for the sensitive detection of pyridoxine

“…Also, Gao et al suggested a nonenzymatic fluorescent sensor for glucose based on silica NPs doped with a europium coordination compound . Sun et al developed a novel biosensor for bovine serum albumin based on fluorescent self‐assembled sandwich bilayers and Sotelo‐Gonzalez et al reported Mn‐doped ZnS QDs for the determination of acetone by phosphorescence attenuation .…”

Mn-doped ZnS quantum dots as a room-temperature phosphorescent probe for analysis of glutamic acid in foodstuffs

“…In particular, Mn 2+ can be well incorporated into the crystal lattice of ZnS because of the equal electric charges and similar ionic radii of Mn 2+ and Zn 2+ . 39 The Mn-doped ZnS QDs show a strong phosphorescence emission at 590 nm when excited at 290 nm. This orange emission band is generated by transition from triplet state to ground state of Mn 2+ when incorporated into the ZnS host lattice.…”
