Turn Broad Into Narrow: Understanding the Pr3+ → Gd3+ Energy Transfer in Cs2NaYCl6
Advanced Optical Materials, Volume 14, Issue 22, 12 June 2026.The energy transfer processes of Pr3+ in elpasolite‐like Cs2NaY1‐xGdxCl6: 1mol%$1 \,\mathrm{mol}\%$ Pr3+ is investigated by steady‐state and time‐resolved spectroscopy. An analysis of the multiexponential decays in the framework of the shell model of energy transfer suggests an occupation of both the Y and Na sites by Pr3+ in this host.

Infrared upconversion for astronomy
, 1977 The basic theory of upconversion is presented, along with a brief historical summary of upconversion techniques. Upconverters were used in astronomical studies, but have met with only modest success. Upconversion will become a useful detection method for

UV TO RED UPCONVERSION EMISSION FROM ERBIUM YTTERBIUM CODOPED BARIUM ZIRCONATE [PDF]
, 2007 "Visible upconversion emission of Er3+ in nanocrystalline BaZrO3 (BZO) powder is obtained under IR excitation in the range between 900 to 1050 nm. In single Er3+ doped BaZrO3 the blue emission was neglected and when Yb3+ is added then it acts as a ...

Aggregate, Volume 7, Issue 6, June 2026.The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.
