“…This can be further classified as aqueous and non-aqueous solvent synthesis routes. Aqueous route is advantages than non-aqueous (organometallic) as it can be performed in low temperature, less toxic and bio-compatible [5,6,[9][10][11][12][13]. The aqueous CdTe synthesis mainly comprises two steps, first preparation of Te precursor and followed by growth of CdTe QDs.…”

“…Te Precursor is prepared by reducing elemental Te in N 2 /inert atmosphere to prevent oxidation of Te [5,6], which increases the cost of reaction. To prevent this, researchers are trying to synthesis CdTe QDs using precursors like Al 2 Te 3 [13,14], Te (as electrode) [9,10], Na 2 TeO 3 [11,12], etc. But, Al 2 Te 3 decompose chemically to produce highly unstable gas H 2 Te which makes the reaction tedious.…”

“…In fact, Te 2-ions are unstable and reactive in aqueous medium; in the presence of small amounts of oxygen, these anions spontaneously oxidize to elemental tellurium and other reduced forms. 36 In addition, heating decomposes the mercapto ligands and releases sulfur into the reaction medium, which possibly diminishes the quantum yield of QDs and leads to loss of ligand functionality. 28,37 To simplify procedures and make them less toxic, researchers have modified the routes that afford QDs.…”

“…A redução do Te 0 por NaBH4 é o processo mais utilizado para preparação de QDs de CdTe-TGA (GAPONIK et al, 2002;RIBEIRO et al, 2013). No entanto, durante o processo de síntese em batelada, observou-se que este procedimento apresenta aspectos experimentais de difícil reprodução, tais como, a coloração da solução de telureto e o tempo necessário para redução de Te 0 para Te 2-.…”

“…No entanto, durante o processo de síntese em batelada, observou-se que este procedimento apresenta aspectos experimentais de difícil reprodução, tais como, a coloração da solução de telureto e o tempo necessário para redução de Te 0 para Te 2-. A produção de telureto é difícil de controlar, devido a alta sensibilidade das espécies formadas no processo (HTe -ou Te 2-) ao oxigênio (DAI et al, 2012;RIBEIRO et al, 2013).…”
