AbstractThe fabrication and optical properties of an erbium-doped gallium phosphide microdisk resonator pumped by a Ti-sapphire laser at 980 nm were investigated. Enhanced Er3+ intra-4f-shell photoluminescence was observed in the microdisk resonator compared to a thin film, and is attributed to a microcavity effect. At low pumping power intensity, the photoluminescence from erbium-doped gallium phosphide microdisks is an order of magnitude more intense than that from a thin film sample.

Resonance Coupling

Silver nanoparticles (Ag NPs) thin film were fabricated by radio-frequency (RF) magnetron sputtering on the quartz substrates in different sputtering time, then covered with a layer of rubrene by means of thermal evaporation. The sputtering time for preparation of Ag NPs could be tuned to increase the spectral overlap between the emission spectra of rubrene and surface plasmon resonance spectra, so that the surface plasmon enhancement was improved. Using a Fluorescence spectrophotometer (FLS920), the photoluminescence (PL) intensity of the rubrene/Ag NPs thin film was up to 22 times higher than that as-deposited rubrene thin film. It is attributed to the energy transfer effect in the surface plasmon resonance coupling, the surface plasmons mediated emission, and light scattering.

Co Doped

Ag and Mn dopants were incorporated into Cu2ZnSnS4 thin film to reduce defects in thin film and improve thin film properties. Sol–gel and spin-coating techniques were employed to deposit Ag and Mn co-doped Cu2ZnSnS4 thin films. The structures, compositions, morphologies, and optical properties of the co-doped thin films were characterized. The experimental results indicate the formation of kesterite structure without Ag and Mn secondary phases. The amount of Ag in the thin films is close to that in the sols. The co-doped Cu2ZnSnS4 thin films have an absorption coefficient of larger than 1.3 × 104 cm−1, a direct optical band gap of 1.54–2.14 eV, and enhanced photoluminescence. The nonradiative recombination in Cu2ZnSnS4 thin film is reduced by Ag and Mn co-doping. The experimental results show that Ag and Mn incorporation can improve the properties of Cu2ZnSnS4 thin film.

Two Dimensional Photonic Crystal

A light-emitting, two-dimensional photonic crystal composed of silicon-rich silicon-dioxide thin film was fabricated by using radio-frequency magnetron sputtering, simple interference exposure, and plasma etching. An enhanced photoluminescence spectrum was observed from the photonic crystal. We found that the photoluminescence peak was located around a wavelength of 830 nm and that the peak intensity was 1.5 times stronger than that from a silicon-rich silicon-dioxide thin film without a periodic structure.
