Abstract
A comparative photoluminescence analysis of as-prepared and chemically modified (by alkyl chains -C18H37) silicon and carbon nanoparticles dispersed in low-polar liquids is reported. Influence of the low-polar liquid nature and ambient temperature on photoluminescence of the nanoparticles has been investigated from the point of view of their possible application as thermal nanoprobes.
Highlights
Low-dimensional structures present considerable interest for researchers because of their new and unique optical and electronic properties in comparison with bulk materials
We have studied the influence of low-polar liquids (LPLs), ambient temperature, and continuous laser irradiation on PL behavior of Si and C NPs in view of their temperature-sensing applications

Summary
Low-dimensional structures present considerable interest for researchers because of their new and unique optical and electronic properties in comparison with bulk materials. Various nanoparticles (NPs) are involved in different applications such as electronics [1], photovoltaic [2], biology [3], liquid crystals [4] etc. Photoluminescence (PL) is one of the important phenomena taking place in semiconductor NPs. It is very sensitive to various experimental conditions, such as molecular ambient environment, temperature, pressure, and so on. Thermally induced PL effects are of special interest for temperature probing at nanoscale in various media. Different materials are reported to be used as thermal-sensitive nanoprobes [5] and nanothermometers [6]
