There are three ways in which the cell efficiency of silicon solar cells may be improved by
better exploitation of the solar spectrum: down-conversion (cutting one high energy photon …

Time-resolved luminescence bioassays based on lanthanide-luminescence probes have
become common, useful tools in clinical diagnostics and bioanalytical chemistry. The unique …

This paper presents an overview of the recent results on upconversion spectroscopy
obtained in our group. After a brief introduction into the upconversion field, three different …

White light was generated from a single silica thin film made with Yb0. 75La0. 2Eu0. 05F3,
La0. 45Yb0. 5Er0. 05F3, and La0. 75Yb0. 2Tm0. 05F3 nanoparticles by exciting with a …

A simple hydrothermal method has been developed for the systematic synthesis of
lanthanide orthophosphate crystals with different crystalline phases and morphologies. It …

The binary luminescence thermometry probe is prepared from Y2O3: Ho3+ and Mg2TiO4:
Mn4+ powders. This probe facilitates self‐referencing temperature readouts with excellent …

We investigated the upconversion properties of nanocrystalline and bulk Y2O3: Er3+ as a
function of the erbium concentration (1, 2, 5, 10, 25, and 35 mol%). Following excitation with …

The effects of the erbium concentration, crystal size, crystal phase, and different processing
temperatures on the upconverted emission of Er3+ in BaTiO3 and TiO2 nanocrystals are …

The improvement of sensitivity is an important issue for optical temperature-sensing
materials. In this work, a series of oxide-based upconversion phosphors were designed by a …

The luminescent properties of 1 mol% Eu3+-doped cubic Lu2O3 nanocrystals prepared by a
combustion synthesis route were investigated. The visible emission spectrum of the …
