Solfuro di piombo (PbS)

Descrizione:

Solfuro di piombo (PbS) è un composto inorganico caratterizzato dalla sua apparenza solida nera ed è principalmente conosciuto per le sue proprietà semiconduttrici. Ha un alto punto di fusione ed è insolubile in acqua, rendendolo stabile in varie condizioni. Il PbS si trova comunemente in natura come il minerale galena, che è una fonte significativa di piombo. Il composto presenta una struttura cristallina cubica ed è notevole per la sua capacità di assorbire radiazioni infrarosse, rendendolo utile in rivelatori infrarossi e applicazioni fotovoltaiche. Il solfuro di piombo può essere sintetizzato attraverso vari metodi, inclusa la reazione di sali di piombo con fonti di solfuro. Tuttavia, è importante notare che il solfuro di piombo è tossico a causa della presenza di piombo, il che comporta rischi ambientali e per la salute. Pertanto, la manipolazione e lo smaltimento devono essere effettuati con cautela, rispettando le normative di sicurezza. Il PbS gioca anche un ruolo nello studio dei punti quantici e dei nanomateriali, dove le sue uniche proprietà elettroniche possono essere sfruttate per applicazioni tecnologiche avanzate.

CAS: 1314-87-0

Lead sulfide quantum dots are semiconductor nanocrystals with a typical size of ~3 nm. They have high values for fluorescence, enzyme activities, and metal hydroxides. Lead sulfide quantum dots can be used to measure the activity of toll-like receptor (TLR) as an analytical method. The fluorescence intensity can be measured using electrochemical impedance spectroscopy (EIS). The fluorescence intensity is proportional to the TLR activity. Optical sensors can detect changes in the fluorescence intensity in real time, which is advantageous for applications that require rapid measurements. Lead sulfide quantum dots have high resistance against plasma mass spectrometry and thermal expansion. This means that they can be used to study the kinetics of reactions involving lead sulfide quantum dots and sodium citrate at different temperatures.
