Chemically etched plastic optical fiber probe for near-field scanning optical microscopy in liquids

Giovanni Dietler, Serguei Sekatski, Anton Smirnov, Kanat Dukenbayev

Some preliminary results and experimental details of Near-field Scanning Optical Microscopy (NSOM) operation in liquids have been reported by us earlier(1-4). Here we present the first use of custom made polystyrene/poly (methyl methacrylate) (PMMA) optica ...

Luminescence studies on photostimulable phosphor CsBr:Eu2+

Giovanni Dietler, Serguei Sekatski, Kanat Dukenbayev

Photostimulable phosphor CsBr:Eu2+ is prepared through a solid-state reaction. The effect of annealing atmosphere on photoluminescence and photostimulated luminescence was investigated. Optimum luminescence intensity was obtained when samples were prepared ...

Near-field scanning optical microscopy using polymethylmethacrylate optical fiber probes

Giovanni Dietler, Mounir Driss Mensi, Serguei Sekatski, Kanat Dukenbayev

We report the first use of polymethylmethacrylate (PMMA) optical fiber-made probes for scanning near-field optical microscopy (SNOM). The sharp tips were prepared by chemical etching of the fibers in ethyl acetate, and the probes were prepared by proper gl ...

Scanning near-field optical microscope based on double-resonant fiber probe montage and its operation in liquids - art. no. 67282D

Giovanni Dietler, Serguei Sekatski, Kanat Dukenbayev

The operation of the scanning near-field optical microscope based on the double-resonant montage of a fiber probe onto the tuning fork (working frequency of the latter, that is 32 kHz, coincides with the second resonance frequency of the bending oscillatio ...
