1：Experimental Design and Method Selection:

The study involves the fabrication of a transparent inorganic-organic nanocomposite film (Y2O3: Eu-PMMA) for solar blind UV light photo-voltage response. The design incorporates Y2O3: Eu nanoparticles into a PMMA matrix coated onto a glass substrate.

2：Sample Selection and Data Sources:

Y2O3: Eu phosphor with optimal luminescence was mixed with PMMA to form a transparent composite film. The film's properties were characterized using various techniques.

3：List of Experimental Equipment and Materials:

X-ray diffractometer (X’Pert PRO), TEM (JEM-2100F), UV–Vis–NIR spectrophotometer (Cary 5000), spectrofluorometer (Edinburgh Instruments FLS920), Si-APD detector.

4：Experimental Procedures and Operational Workflow:

The Y2O3: Eu phosphor was synthesized and mixed with PMMA to form a film. The film was characterized for its luminescent properties and photo-voltage response under UV light.

5：Data Analysis Methods:

The luminescence and photo-voltage response data were analyzed to evaluate the film's performance in solar blind UV light detection.
