Silicon based light emitting gels

Light emitting properties of a silicon-containing gel formed by the controlled reaction between acetone and tetrachlorosilane is reported here. Although infrared spectroscopic analysis shows that the gel has a siloxane network (1000–1100 cm−1), UV absorption with a maximum of 328 nm suggests that it is not a simple siloxane polymer. A photoluminescence (PL) spectrum of the compound gives a broad peak in the range of 800–950 nm, attributed to the structural features associated with carbonyl conjugated siloxane groups.
