Accessing photoresponsive copper selenide nanomaterials and thin films through tetranuclear Cu(I) pyridylselenolate cluster

Synthesis of photoresponsive and photoemissive ultrathin 2D nanosheets of In2S3 achieved through a new single source molecular precursor

“…The matching t rise and t fall is an indication of the involvement of less trap states or defects in the switching process. 38,39 The appreciable performance of ultrathin In 2 S 3 NSs is probably due to the unique morphology of the same by virtue of which it allows direct access to charge carriers with very high mobility. 40 A comparative study of the photoresponse performance of the In 2 S 3 NSs with some of the previous reports with different morphologies of In 2 S 3 along with some other 2D materials (Table 3) reveals equivalent performance.…”

Influence of the electrochemical processing parameters on the photocurrent–voltage conversion characteristics of copper bismuth selenide photoactive films

“…Hence, it is essential to calculate the current efficiency to identify the ratio of the current devoted to the main electrodeposition reaction that serves to form the target films. The ratio between the partial current of the main process of interest and the overall applied current is the current efficiency (CE) percentage [34]. Theoretical weight can be calculated from the first law of Faraday for electrodeposition and substituting in Eq.…”

“…Normally, the deposition process proceeds through different primary proposed reactions from ( 10) to ( 14) concluded from the XRD and XPS, and EDS analysis as follows: phase with the tetragonal crystal structure (JCPDS # 01-072-1421) [34]. In addition, a minor phase of CuSe alloy that matching the reference card (JCPDs#034-0171) was noticed as small peaks in the XRD pattern.…”

Facile one pot synthesis of highly photoresponsive coinage metal selenides (Cu1.8Se and Ag2Se) achieved through novel Cu and Ag pyridylselenolates as molecular precursors

“…18,19 Despite this, only a handful of SSPs have been developed and utilized to produce coinage metal chalcogenides. [20][21][22][23][24][25][26][27] Some early reports on the preparation of copper selenides through molecular precursors include the utilization of metal chalcogenolates, selenocarbamates, phosphine diselenolates, etc. For instance, Brennan and co-workers utilized copper selenolates [Cu(2-SeNC 5 H 4 )] 4 and [Cu(3-Me 3 Si-2-SeNC 5 H 3 )] 4 to prepare the Cu 2−x Se material.…”
