“…[13][14][15] In recent years, luminescent nanocrystals of rare-earth (RE) metals attract a great deal of attention because of their potential applications for displays, 16 17 solid state lasers, 18 optical telecommunication, 19 optical amplifiers [20][21][22] and biolabeling. [23][24][25] On account of their intriguing physical, magnetic and luminescent properties, RE nanomaterials such as oxides, [26][27][28] phosphates, 29 fluorides, [30][31][32] vanadates, 33 oxalates, [34][35][36] tantalates, 37 38 tungstets, 39 sulphides 40 and RE ions doped inorganic nanophosphors have now become a new focus of research in nanoscience. The oxalate family among RE compounds stands out by reason of their wide applications.…”

Polycrystalline lanthanum oxalate (LaOX) nanorods (NRs) were succesfully synthesized using reverse micellar (RM) method. The study espouses the versatility of the reverse micellar method forming monodisperse, stable nanorods at room temperature. The as-synthesized LaOX nanorods were characterised by different techniques. Result shows that the nanorods of LaOX with aspect ratio 10.2:1 have preferred growth direction of (020). The pure phase synthesis of the nanorods was confirmed from Fourier transformed infrared (FTIR) and X-ray diffraction (XRD) analysis. The thermo gravimetric analysis (TGA) and differential thermal analysis (DTA) of the as-synthesized nanorods were perfomed to observe their thermal degradation. Synthesized nanorods are fluorescent having emission maximum at 329 nm. Fluorescence resonance energy transfer (FRET) phenomenon has been observed between LaOX nanorods (energy donor) and naphthalimide (NAP) derivative (energy acceptor) and this mechanism can be helpful for sensing of NAP or NAP like molecules used as antioxidative in living systems.

Optical Properties of Functional Hybrid Organic–Inorganic Nanocomposites

Functional hybrids are nanocomposite materials lying at the interface of organic and inorganic realms, whose high versatility offers a wide range of possibilities to elaborate tailor‐made materials in terms of chemical and physical properties. Because they present several advantages for designing materials for optical applications (versatile and relatively facile chemistry, easy shaping and patterning, materials having good mechanical integrity and excellent optical quality), numerous silica or/and siloxane based hybrid organic–inorganic materials have been developed in the past few years. The most striking examples of functional hybrids exhibiting emission properties (solid‐state dye lasers, rare‐earth doped hybrids, electroluminescent devices), absorption properties (photochromic), nonlinear optical (NLO) properties (second‐order NLO properties, photochemical hole burning (PHB), photorefractivity), and sensing are summarized in this review.
