Abstract Nanocrystalline highly Fe-doped SnO 2 thin films were prepared using a new
simple sol-gel method with iron amounts of 5, 10, 15 and 20%. The obtained gel offers a …

A photoconversion device was fabricated based on SnO 2 film prepared by a chemical spray
pyrolysis technique. The SnO 2 nanofilms were grown on the porous silicon (PS) …

The report summarizes peculiarities of synthesis and luminescence properties of porous
silicon, porous anodic alumina and artificial opals with the inclusions of sol-gel derived …

In this work, a colloid of nanocrystalline ZnO particles was prepared by chemical method,
and sprayed on porous silicon (PS) substrate which was prepared by electrochemical …

We have investigated the optical properties of sol–gel thin films of tin dioxide (SnO2)
codoped with Er3+–Yb3+ as a function of Yb3+ concentration. The Judd–Ofelt model has …

In this work, we synthesised xerogels embedded in honeycomb porous anodic alumina films
of 1–150μm thickness, with pore diameters of 40–180nm and cell sizes of 120–250nm, and …

A CdS/Si nanoheterostructure was prepared by growing CdS nanocrystallites onto silicon
nanoporous pillar array. A rectification effect with an onset voltage of∼ 1 V⁠, a forward …

SnO2 thin films undoped and doped with antimony (Sb), erbium (Er) and Si nanocrystals (Si-
nc) have been grown on silicon (Si) substrate using sol–gel method. Room-temperature …

Porous anodic alumina matrices covered with spin-on erbium-doped In2O3 xerogel films
have been synthesized and investigated by photoluminescence (PL) spectroscopy. At room …

Structures comprising a xerogel, doped with lanthanide ions (erbium, terbium and
europium), embedded in porous anodic alumina (PAA) have been fabricated and their …
